Red Hat Bugzilla – Bug 81157
Buffer overflow issue in libpng
Last modified: 2013-04-02 00:17:33 EDT
Unpatched versions of libpng 1.2.1 and earlier do not correctly calculate
offsets, which leads to a buffer overflow and the possibility of arbitrary
code execution. This could be exploited by an attacker creating a
carefully crafted PNG file which could execute arbitrary code when the
victim views it.
Packages within Red Hat Linux, such as Mozilla, make use of the shared
libpng library. Therefore, all users are advised to upgrade to the errata
We're working on an erratum which will contain a backported fix for this issue
to libpng 1.0.14
An errata has been issued which should help the problem described in this bug report.
This report is therefore being closed with a resolution of ERRATA. For more information

this bug report if the solution does not work for you.
