Fedora 32: 2020-d67cc48dce moderate: pngcheck Executable Hardening

fedora
Calendar Grey November 5, 2020
Scroller Fedora
Enhances executable fortification within pngcheck for Fedora 32 to bolster security protocols.
Fix executable hardening (PIC/PIE)

Summary

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.
