Changelog for libgcrypt20-32bit-1.7.8-136.1.x86_64.rpm :
Thu Jun 29 14:00:00 2017 astiegerAATTsuse.com
- libgcrypt 1.7.8:

* CVE-2017-7526: Mitigate a flush+reload side-channel attack on
RSA secret keys (bsc#1046607)

Sun Jun 4 14:00:00 2017 astiegerAATTsuse.com
- libgcrypt 1.7.7:

* Fix possible timing attack on EdDSA session key (previously
patched, drop libgcrypt-secure-EdDSA-session-key.patch)

* Fix long standing bug in secure memory implementation which
could lead to a segv on free

Fri Jun 2 14:00:00 2017 pmonrealgonzalezAATTsuse.com
- Added libgcrypt-secure-EdDSA-session-key.patch [bsc#1042326]

* Store the session key in secure memory to ensure that constant
time point operations are used in the MPI library.

Fri Jan 20 13:00:00 2017 rmaliskaAATTsuse.com
- libgcrypt 1.7.6:

* Fix counter operand from read-only to read/write

* Fix too large jump alignment in mpih-rshift

Thu Dec 15 13:00:00 2016 astiegerAATTsuse.com
- libgcrypt 1.7.5:

* Fix regression in mlock detection introduced with 1.7.4

Tue Dec 13 13:00:00 2016 astiegerAATTsuse.com
- libgcrypt 1.7.4:

* ARMv8/AArch32 performance improvements for AES, GCM, SHA-256,
and SHA-1.

* Add ARMv8/AArch32 assembly implementation for Twofish and
Camellia.

* Add bulk processing implementation for ARMv8/AArch32.

* Add Stribog OIDs.

* Improve the DRBG performance and sync the code with the Linux
version.

* When secure memory is requested by the MPI functions or by
gcry_xmalloc_secure, they do not anymore lead to a fatal error
if the secure memory pool is used up. Instead new pools are
allocated as needed. These new pools are not protected against
being swapped out (mlock can\'t be used). Mitigation for
minor confidentiality issues is encryption swap space.

* Fix GOST 28147 CryptoPro-B S-box.

* Fix error code handling of mlock calls.
