Summary: Verifies the integrity of PNG, JNG and MNG files |
pngcheck verifies the integrity of PNG, JNG and MNG files (by checking the internal 32-bit CRCs [checksums] and decompressing the image data); it can optionally dump almost all of the chunk-level information in the image in human-readable form. For example, it can be used to print the basic statistics about an image (dimensions, bit depth, etc.); to list the color and transparency info in its palette (assuming it has one); or to extract the embedded text annotations. This is a command-line program with batch capabilities. The current release supports all PNG, MNG and JNG chunks, including the newly approved sTER stereo-layout chunk. It correctly reports errors in all but two of the images in Chris Nokleberg's brokensuite-20061204.

* Mon Apr 26 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 2.4.0-8 - Backport fix for RHBZ#1949800 from upstream release 3.0.3 * Thu Jan 07 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 2.4.0-7 - Fix buffer overflow on large MNG LOOP chunk (RHBZ#1908559) * Thu Jan 07 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 2.4.0-6 - Fix a buffer overrun for certain invalid MNG PPLT chunk contents (RHBZ#1907428). * Mon Dec 14 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 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 <code@musicinmybrain.net> - 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 <code@musicinmybrain.net> - 2.3.0-5 - Fix null pointer dereference in pngcheck when -f is given and the sCAL chunk is missing the pixel height. * Fri Nov 13 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-4 - Fix buffer overflow (RHBZ #1897485) * Wed Oct 28 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-3 - Add _hardened_build macro for EPEL * Wed Oct 28 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-2 - Work around Makefile.unx not actually using LDFLAGS; this fixes hardened build (PIE) * Thu Oct 15 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-1 - Initial import (#1886858)
