Fedora 32: FEDORA-2021-eb5d6cf9f6 Moderate: pngcheck Integer Issue

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.

Backported fix for #1949800, in which certain invalid PNG data could cause an

integer division-by-zero, invoking undefined behavior, from upstream release

3.0.3.
