2021-02-09 00:56:15.132383
--------------------------------------------------------------------------------Name        : pngcheck
Product     : Fedora 33
Version     : 2.4.0
Release     : 7.fc33
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:

Buffer overflow fixes: 1. Fix buffer overflow on large MNG LOOP chunk
(RHBZ#1908559). 2. Fix a buffer overrun for certain invalid MNG PPLT chunk
contents (RHBZ#1907428).
