fedora
Calendar Grey December 31, 2015
Dist Fedora Esm H88
An update to Fedora's libpng10 addresses a critical underflow issue that could lead to out-of-bounds reads when handling PNG images.
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.
