Changelog for clamav-0.104.2-59.3.x86_64.rpm :

* Wed Jan 12 2022 Arjen de Korte - Update to 0.104.2
* CVE-2022-20698: Fix for invalid pointer read that may cause a crash. Affects 0.104.1, 0.103.4 and prior when ClamAV is compiled with libjson-c and the CL_SCAN_GENERAL_COLLECT_METADATA scan option (the clamscan --gen-json option) is enabled.
* Fixed ability to disable the file size limit with libclamav C API, like this: cl_engine_set_num(engine, CL_ENGINE_MAX_FILESIZE, 0); This issue didn\'t impact ClamD or ClamScan which also can disable the limit by setting it to zero using MaxFileSize 0 in clamd.conf for ClamD, or clamscan --max-filesize=0 for ClamScan. Note: Internally, the max file size is still set to 2 GiB. Disabling the limit for a scan will fall back on the internal 2 GiB limitation.
* Increased the maximum line length for ClamAV config files from 512 bytes to 1,024 bytes to allow for longer config option strings.
* Wed Nov 03 2021 Arjen de Korte - Update to 0.104.1
* FreshClam: - Add a 24-hour cool-down for FreshClam clients that have received an HTTP 403 (Forbidden) response from the CDN. This is to reduce the volume of 403-response data served to blocked FreshClam clients that are configured with a tight update-loop. - Fixed a bug where FreshClam treats an empty CDIFF as an incremental update failure instead of as an intentional request to download the whole CVD.
* ClamDScan: Fix a scan error when broken symlinks are encountered on macOS with \"FollowDirectorySymlinks\" and \"FollowFileSymlinks\" options disabled.
* Overhauled the scan recursion / nested archive extraction logic and added new limits on embedded file-type recognition performed during the \"raw\" scan of each file. This limits embedded file-type misidentification and prevents detecting embedded file content that is found/extracted and scanned at other layers in the scanning process.
* Fix an issue with the FMap module that failed to read from some nested files.
* Fixed an issue where failing to load some rules from a Yara file containing multiple rules may cause a crash.
* Fixed assorted compiler warnings.
* Fixed assorted Coverity static code analysis issues.
* Scan limits: - Added virus-name suffixes to the alerts that trigger when a scan limit has been exceeded. Rather than simply Heuristics.Limits.Exceeded, you may now see limit-specific virus-names, to include: + Heuristics.Limits.Exceeded.MaxFileSize + Heuristics.Limits.Exceeded.MaxScanSize + Heuristics.Limits.Exceeded.MaxFiles + Heuristics.Limits.Exceeded.MaxRecursion + Heuristics.Limits.Exceeded.MaxScanTime - Renamed the Heuristics.Email.ExceedsMax.
* alerts to align with the other limit alerts names. These alerts include: + Heuristics.Limits.Exceeded.EmailLineFoldcnt + Heuristics.Limits.Exceeded.EmailHeaderBytes + Heuristics.Limits.Exceeded.EmailHeaders + Heuristics.Limits.Exceeded.EmailMIMEPartsPerMessage + Heuristics.Limits.Exceeded.EmailMIMEArguments - Fixed an issue where the Email-related scan limits would alert even when the \"AlertExceedsMax\" (--alert-exceeds-max) scan option is not enabled. - Fixes an issue in the Zip parser where exceeding the \"MaxFiles\" limit or the \"MaxFileSize\" limit would abort the scan but would fail to alert.
* Fixed a leak in the Email parser when using the --gen-json scan option.
* Fixed an issue where a failure to record metadata in the Email parser when using the --gen-json scan option could cause the Email parser to abort the scan early and fail to extract and scan additional content.
* Fixed a file name memory leak in the Zip parser.
* Fixed an issue where certain signature patterns may cause a crash or cause unintended matches on some systems when converting characters to uppercase if a UTF-8 unicode single-byte grapheme becomes a multi-byte grapheme.
* CMake: - Fix a packaging issue with the Windows
*.msi installer so that it will include all of the required files. - Add support for developer code-signing on macOS during the build. - Fix an issue finding and linking with the tinfo library on systems where tinfo is separate from ncurses.
* Tests: Improved the Freshclam incremental update tests to verify correct behavior when a zero-byte CDIFF is downloaded and the CVD served to FreshClam is older than advertised.
* Docker: Remove the freshclam.dat file when building the Docker image with the databases-included so FreshClam agents running in the container will have a unique ID in the HTTP User-Agent.
* Fri Sep 03 2021 Arjen de Korte - Update to 0.104.0
* As of ClamAV 0.104, CMake is required to build ClamAV.
* The Autotools and the Visual Studio build systems have been removed.
* The built-in LLVM for the bytecode runtime has been removed.
* The bytecode interpreter is the default runtime for bytecode signatures just as it was in ClamAV 0.103.- Package HTML documentation in separate subpackage- Remove obsolete patch and rewrite patch to disable yara - clamav-ck_assert_msg.patch % clamav-disable-yara.patch- Don\'t use syslog for freshclam.service logging and don\'t listen on TCP socket for clamd.service (only UNIX domain socket). This was already changed in 0.103.3, but was not mentioned in the changelog. % clamav-conf.patch
* Mon Jun 21 2021 Arjen de Korte - Update to 0.103.3
* Fixed a scan performance issue when ENGINE_OPTIONS_FORCE_TO_DISK is enabled. This issue did not impacted most users but for those affected it caused every scanned file to be copied to the temp directory before the scan.
* Fix ClamDScan crashes when using the --fdpass --multiscan command-line options in combination with the ClamD ExcludePath config file options.
* Fixed an issue where the mirrors.dat file is owned by root when starting as root (or with sudo) and using daemon-mode. File ownership will be set to the DatabaseOwner just before FreshClam switches to run as that user.
* Renamed the mirrors.dat file to freshclam.dat.
* Disabled the HTTPUserAgent config option if the DatabaseMirror uses clamav.net. This will prevent users from being inadvertently blocked and will ensure that we can keep better metrics on which ClamAV versions are being used.
* Moved the detection for Heuristics.PNG.CVE-2010-1205 behind the ClamScan --alert-broken-media option (ClamD AlertBrokenMedia yes) option. This type of PNG issue appears to be common enough to be an annoyance, and the CVE is old enough that no one should be vulnerable at this point.
* Fix ClamSubmit failures after changes to Cloudflare \"__cfduid\" cookies. See: https://blog.cloudflare.com/deprecating-cfduid-cookie/
* Fri Apr 09 2021 Reinhard Max - Use a split-provides for clamav-milter instead of recommending it.
* Wed Apr 07 2021 Arjen de Korte - Update to 0.103.2
* CVE-2021-1252, bsc#1184532: Fix for Excel XLM parser infinite loop. Affects 0.103.0 and 0.103.1 only.
* CVE-2021-1404, bsc#1184533: Fix for PDF parser buffer over-read; possible crash. Affects 0.103.0 and 0.103.1 only.
* CVE-2021-1405, bsc#1184534: Fix for mail parser NULL-dereference crash. Affects 0.103.1 and prior.
* Fix possible memory leak in PNG parser.
* Fix ClamOnAcc scan on file-creation race condition so files are scanned after their contents are written.
* FreshClam: Deprecate the SafeBrowsing config option. The SafeBrowsing option will no longer do anything.
* For more details, see our blog post from last year about the future of the ClamAV Safe Browsing database.
* FreshClam: Improved HTTP 304, 403, & 429 handling.
* FreshClam: Added back the mirrors.dat file to the database directory.
* FreshClam will now exit with a failure in daemon mode if an HTTP 403 (Forbidden) was received, because retrying later won\'t help any. The FreshClam user will have to take actions to get unblocked.
* Fix the FreshClam mirror-sync issue where a downloaded database is \"older than the version advertised.\"
* bsc#1181256: Fix errors when scanning files > 4G- Update package signing key (from https://www.clamav.net/downloads) % clamav.keyring
* Thu Feb 25 2021 Arjen de Korte - Package clamav-milter in a subpackage- Remove virus signatures upon uninstall- Check for database existence before starting clamd- Restart clamd when it exits
* Tue Feb 09 2021 Arjen de Korte - Don\'t daemonize freshclam, but use a systemd timer instead to trigger updates + timer.freshclam % service.freshclam % clamav-conf.patch- Remove obsolete patch (replaced by SOURCE_DATE_EPOCH) - clamav-disable-timestamps.patch- Fix unit test + clamav-ck_assert_msg.patch- Cleanup spec
* use pkgconfig() to resolve BuildRequires where upstream uses it
* rework creating vscan user (new system-user in Tumbleweed)
* remove obsolete configure option --disable-zlib-vcheck
* Sat Feb 06 2021 Arjen de Korte - Update to 0.103.1
* Added a new scan option to alert on broken media (graphics) file formats. This feature mitigates the risk of malformed media files intended to exploit vulnerabilities in other software. At present media validation exists for JPEG, TIFF, PNG, and GIF files. To enable this feature, set AlertBrokenMedia yes in clamd.conf, or use the --alert-broken-media option when using clamscan. These options are disabled by default in this patch release, but may be enabled in a subsequent release. Application developers may enable this scan option by enabling CL_SCAN_HEURISTIC_BROKEN_MEDIA for the heuristic scan option bit field.
* Added CL_TYPE_TIFF, CL_TYPE_JPEG types to match GIF, PNG typing behavior. BMP and JPEG 2000 files will continue to detect as CL_TYPE_GRAPHICS because ClamAV does not yet have BMP or JPEG 2000 format checking capabilities.
* Fixed PNG parser logic bugs that caused an excess of parsing errors and fixed a stack exhaustion issue affecting some systems when scanning PNG files. PNG file type detection was disabled via signature database update for ClamAV version 0.103.0 to mitigate the effects from these bugs.
* Fixed an issue where PNG and GIF files no longer work with Target:5 graphics signatures if detected as CL_TYPE_PNG/GIF rather than as CL_TYPE_GRAPHICS. Target types now support up to 10 possible file types to make way for additional graphics types in future releases.
* Fixed clamonacc\'s --fdpass option. - Interprocess file descriptor passing for clamonacc was broken since version 0.102.0 due to a bug introduced by the switch to curl for communicating with clamd. On Linux, passing file descriptors from one process to another is handled by the kernel, so we reverted clamonacc to use standard system calls for socket communication when fd passing is enabled.
* Fixed a clamonacc stack corruption issue on some systems when using an older version of libcurl.
* Allow clamscan and clamdscan scans to proceed even if the realpath lookup failed. This alleviates an issue on Windows scanning files hosted on file- systems that do not support the GetMappedFileNameW() API such as on ImDisk RAM-disks.
* Fixed freshclam --on-update-execute=EXIT_1 temporary directory cleanup issue.
* clamd\'s log output and VirusEvent now provide the scan target\'s file path instead of a file descriptor. The clamd socket API for submitting a scan by FD-passing doesn\'t include a file path, this feature works by looking up the file path by file descriptor. This feature works on Mac and Linux but is not yet implemented for other UNIX operating systems. FD-passing is not available for Windows.
* Fixed an issue where freshclam database validation didn\'t work correctly when run in daemon mode on Linux/Unix.
* Thu Nov 12 2020 Dominique Leuenberger - Do not hard-depend on systemd: use systemd_ordering instead of systemd_requires.
* Tue Nov 10 2020 Reinhard Max - Sync Factory to SLE-15 to implement jsc#ECO-3010 and bsc#1118459.- bsc#1119353, clamav-fips.patch: Fix freshclam crash in FIPS mode.- Keep OBS from installing an existing clamav instance to scan the sources, because this makes \"make check\" use the old library instead of the just built one. This is only a workaround until we found a way to keep libtool from adding libdir to rpath and LD_LIBRARY_PATH of the binaries in the testsuite.
* Mon Sep 14 2020 Arjen de Korte - Update to 0.103.0
* clamd can now reload the signature database without blocking scanning. This multi-threaded database reload improvement was made possible thanks to a community effort. - Non-blocking database reloads are now the default behavior. Some systems that are more constrained on RAM may need to disable non-blocking reloads as it will temporarily consume two times as much memory. We added a new clamd config option ConcurrentDatabaseReload, which may be set to no.
* Dropped clamav-str-h.patch (no longer needed)
* Fix clamav-milter.service (requires clamd.service to run)
* Thu Jul 16 2020 Arjen de Korte - Update to 0.102.4
* CVE-2020-3350: Fix a vulnerability wherein a malicious user could replace a scan target\'s directory with a symlink to another path to trick clamscan, clamdscan, or clamonacc into removing or moving a different file (eg. a critical system file). The issue would affect users that use the --move or --remove options for clamscan, clamdscan, and clamonacc.
* CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing module in ClamAV 0.102.3 that could cause a Denial-of-Service (DoS) condition. Improper bounds checking results in an out-of-bounds read which could cause a crash. The previous fix for this CVE in 0.102.3 was incomplete. This fix correctly resolves the issue.
* CVE-2020-3481: Fix a vulnerability in the EGG archive module in ClamAV 0.102.0 - 0.102.3 could cause a Denial-of-Service (DoS) condition. Improper error handling may result in a crash due to a NULL pointer dereference. This vulnerability is mitigated for those using the official ClamAV signature databases because the file type signatures in daily.cvd will not enable the EGG archive parser in versions affected by the vulnerability.
* Tue May 12 2020 Arjen de Korte - Update to 0.102.3
* CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing module in ClamAV 0.102.2 that could cause a Denial-of-Service (DoS) condition. Improper bounds checking of an unsigned variable results in an out-of-bounds read which causes a crash.
* CVE-2020-3341: Fix a vulnerability in the PDF parsing module in ClamAV 0.101 - 0.102.2 that could cause a Denial-of-Service (DoS) condition. Improper size checking of a buffer used to initialize AES decryption routines results in an out-of-bounds read which may cause a crash.
* Fix \"Attempt to allocate 0 bytes\" error when parsing some PDF documents.
* Fix a couple of minor memory leaks.
* Updated libclamunrar to UnRAR 5.9.2.
* Wed Apr 01 2020 Martin Pluskal - Drop python build dependency as it is not needed
* Wed Feb 05 2020 Arjen de Korte - update to 0.102.2
* CVE-2020-3123: A denial-of-service (DoS) condition may occur when using the optional credit card data-loss-prevention (DLP) feature. Improper bounds checking of an unsigned variable resulted in an out-of-bounds read, which causes a crash.
* Significantly improved the scan speed of PDF files on Windows.
* Re-applied a fix to alleviate file access issues when scanning RAR files in downstream projects that use libclamav where the scanning engine is operating in a low-privilege process. This bug was originally fixed in 0.101.2 and the fix was mistakenly omitted from 0.102.0.
* Fixed an issue where freshclam failed to update if the database version downloaded is one version older than advertised. This situation may occur after a new database version is published. The issue affected users downloading the whole CVD database file.
* Changed the default freshclam ReceiveTimeout setting to 0 (infinite). The ReceiveTimeout had caused needless database update failures for users with slower internet connections.
* Correctly display the number of kilobytes (KiB) in progress bar and reduced the size of the progress bar to accommodate 80-character width terminals.
* Fixed an issue where running freshclam manually causes a daemonized freshclam process to fail when it updates because the manual instance deletes the temporary download directory. The freshclam temporary files will now download to a unique directory created at the time of an update instead of using a hardcoded directory created/destroyed at the program start/exit.
* Fix for freshclam\'s OnOutdatedExecute config option.
* Fixes a memory leak in the error condition handling for the email parser.
* Improved bound checking and error handling in ARJ archive parser.
* Improved error handling in PDF parser.
* Fix for memory leak in byte-compare signature handler.
* Tue Dec 24 2019 Arjen de Korte - The freshclam.service should not be started before the network is online (it checks for updates immediately upon service start)
* Thu Dec 19 2019 Dominique Leuenberger - BuildRequire pkgconfig(libsystemd) instead of systemd-devel: Allow OBS to shortcut through the -mini flavors.
* Wed Nov 20 2019 Arjen de Korte - update to 0.102.1
* CVE-2019-15961, bsc#1157763: A Denial-of-Service (DoS) vulnerability may occur when scanning a specially crafted email file as a result of excessively long scan times. The issue is resolved by implementing several maximums in parsing MIME messages and by optimizing use of memory allocation.
* Build system fixes to build clamav-milter, to correctly link with libxml2 when detected, and to correctly detect fanotify for on-access scanning feature support.
* Signature load time is significantly reduced by changing to a more efficient algorithm for loading signature patterns and allocating the AC trie. Patch courtesy of Alberto Wu.
* Introduced a new configure option to statically link libjson-c with libclamav. Static linking with libjson is highly recommended to prevent crashes in applications that use libclamav alongside another JSON parsing library.
* Null-dereference fix in email parser when using the - -gen-json metadata option.
* Fixes for Authenticode parsing and certificate signature (.crb database) bugs.- dropped clamav-fix_building_milter.patch (upstreamed)
* Fri Nov 01 2019 Arjen de Korte - update to 0.102.0
* The On-Access Scanning feature has been migrated out of clamd and into a brand new utility named clamonacc. This utility is similar to clamdscan and clamav-milter in that it acts as a client to clamd. This separation from clamd means that clamd no longer needs to run with root privileges while scanning potentially malicious files. Instead, clamd may drop privileges to run under an account that does not have super-user. In addition to improving the security posture of running clamd with On-Access enabled, this update fixed a few outstanding defects: - On-Access scanning for created and moved files (Extra-Scanning) is fixed. - VirusEvent for On-Access scans is fixed. - With clamonacc, it is now possible to copy, move, or remove a file if the scan triggered an alert, just like with clamdscan.
* The freshclam database update utility has undergone a significant update. This includes: - Added support for HTTPS. - Support for database mirrors hosted on ports other than 80. - Removal of the mirror management feature (mirrors.dat). - An all new libfreshclam library API.- created new subpackage libfreshclam2- dropped clamav-max_patch.patch (upstreamed)- added clamav-fix_building_milter.patch to fix build of milter
* Fri Oct 25 2019 Reinhard Max - bsc#1151839: Increase the startup timeout of clamd to 5 minutes to cater for the grown virus database as a workaround until clamd has learned to talk to systemd to extend the timeout as long as needed.
* Wed Sep 04 2019 Andreas Stieger - update to 0.101.4:
* CVE-2019-12900: An out of bounds write in the NSIS bzip2 (boo#1149458)
* CVE-2019-12625: Introduce a configurable time limit to mitigate zip bomb vulnerability completely. Default is 2 minutes, configurable useing the clamscan --max-scantime and for clamd using the MaxScanTime config option (boo#1144504)
* Tue Aug 06 2019 Reinhard Max - Update to version 0.101.3:
* bsc#1144504: ZIP bomb causes extreme CPU spikes
* Wed Mar 27 2019 Andrey Karepin - Update to version 0.101.2 (bsc#1130721)
* CVE-2019-1787: An out-of-bounds heap read condition may occur when scanning PDF documents. The defect is a failure to correctly keep track of the number of bytes remaining in a buffer when indexing file data.
* CVE-2019-1789: An out-of-bounds heap read condition may occur when scanning PE files (i.e. Windows EXE and DLL files) that have been packed using Aspack as a result of inadequate bound-checking.
* CVE-2019-1788: An out-of-bounds heap write condition may occur when scanning OLE2 files such as Microsoft Office 97-2003 documents. The invalid write happens when an invalid pointer is mistakenly used to initialize a 32bit integer to zero. This is likely to crash the application.
* CVE-2019-1786: An out-of-bounds heap read condition may occur when scanning malformed PDF documents as a result of improper bounds-checking.
* CVE-2019-1785: A path-traversal write condition may occur as a result of improper input validation when scanning RAR archives.
* CVE-2019-1798: A use-after-free condition may occur as a result of improper error handling when scanning nested RAR archives.- added clamav-max_patch.patch to fix build- dropped clamav-freshclam-exit.patch
* Mon Jan 21 2019 Reinhard Max - Update to version 0.101.1:
* Add missing headers to fix build of packages against libclamav.- Add missing include for str.h to libclamav/others_common.c (clamav-str-h.patch)
