Changelog for libpng12-devel-1.2.59-80.9.x86_64.rpm :

* Fri Mar 01 2024 pgajdosAATTsuse.com- Use %autosetup macro. Allows to eliminate the usage of deprecated %patchN
* Wed May 04 2022 Marcus Meissner - switched to https url
* Wed Jul 17 2019 pgajdosAATTsuse.com- version update to 1.2.59 Added png_check_chunk_length() function, and check all chunks except IDAT against the default 8MB limit; check IDAT against the maximum size computed from IHDR parameters (Fixes CVE-2017-12652). Initialize memory allocated by png_inflate to zero, using memset, to stop an oss-fuzz \"use of uninitialized value\" detection in png_set_text_2() due to truncated iTXt or zTXt chunk.
* Wed Jan 31 2018 pgajdosAATTsuse.com- check with -j1, be explicit
* Tue Jan 30 2018 jengelhAATTinai.de- Fix SRPM group and grammar issues.
