-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2021-e24167b0e8 2021-02-09 01:07:37.998866 -------------------------------------------------------------------------------- Name : pngcheck Product : Fedora 32 Version : 2.4.0 Release : 7.fc32 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.
