Dist Fedora Esm H88
Critical Fedora patch released for libpng16 to rectify an overflow vulnerability in png_verify_keyword, enhancing security measures.
An underflow read was found in png_check_keyword in libpng10

Summary

The libpng10 package contains an old version of libpng, a library of functions

for creating and manipulating PNG (Portable Network Graphics) image format

files.

This package is needed if you want to run binaries that were linked dynamically

with libpng 1.0.x.

Update Information:

An underflow read was found in png_check_keyword in libpng10. An attacker could possibly use this flaw to cause an out-of-bounds read by tricking an unsuspecting user into processing a specially crafted PNG image.
