Changelog for pngcheck-debugsource-2.4.0-7.el8.x86_64.rpm :

* Thu Jan 07 2021 Benjamin A. Beasley - 2.4.0-7- Fix buffer overflow on large MNG LOOP chunk (RHBZ#1908559)
* Thu Jan 07 2021 Benjamin A. Beasley - 2.4.0-6- Fix a buffer overrun for certain invalid MNG PPLT chunk contents (RHBZ#1907428).
* Mon Dec 14 2020 Benjamin A. Beasley - 2.4.0-5- Previous fix for buffer overrun printing the contents of the sPLT chunk in certain malformed inputs (RHBZ#1905775) was incomplete; it should be properly fixed now.
* Sun Dec 13 2020 Benjamin A. Beasley - 2.4.0-4- Bounds-check all accesses into enumerated-value name arrays; a malformed file could have caused a buffer overrun in several of these cases. (RHBZ#1902810)- Fix buffer overrun when print_buffer() is passed a nonpositive size, which can occur in practice for certain malformed inputs. (RHBZ#1902810)- In some cases, the chunk length from the file data (sz) is used to index into the read buffer without sufficient bounds-checking, leading to a buffer overrun. Fix this for PPLT, hIST, sCAL, FRAM, SAVE, nEED, PAST, DISC, DROP, DBYK, ORDR, and SEEK chunks. (RHBZ#1902810)- Fix buffer overrun printing the contents of the sPLT chunk in certain malformed inputs. (RHBZ#1905775)- Backport fix for off-by-one bug in check_magic() from 3.0.0- Backport fix for zlib version warnings going to stdout from 3.0.0- Use name macro when referencing patches.- Add BR on make in anticipation of https://fedoraproject.org/wiki/Changes/Remove_make_from_BuildRoot.- New upstream version 2.4.0- Added new license file for main package (same MIT-style license)- Drop format-security patch, now upstreamed- Use upstreamed man pages; no need to generate with help2man anymore- Add rpmlintrc rules for -extras subpackage- Add rpmlintrc file to suppress spurious rpmlint warnings
* Mon Nov 30 2020 Benjamin A. Beasley - 2.3.0-5- Fix null pointer dereference in pngcheck when -f is given and the sCAL chunk is missing the pixel height.
