Fedora 34: 2021-3f001ba18b Critical: Pngcheck Undefined Behavior

New upstream release 3.0.3. Fixes #1949800, in which certain invalid PNG data could cause an integer division-by-zero, invoking undefined behavior.. --------------------------------------------------------------------------------Fedora Update Notification FEDORA-2021-3f001ba18b 2021-05-05 01:20:25.877430 --------------------------------------------------------------------------------Name : pngcheck Product : Fedora 34 Version : 3.0.3 Release : 1.fc34 URL : http://www.libpng.org/pub/png/apps/pngcheck.html Summary : Verifies the integrity of PNG, JNG and MNG files Description : 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. --------------------------------------------------------------------------------Update Information: New upstream release 3.0.3.
