Check for the version of the libpng packages Detailed Explanation for this Vulnerability Assessment Updated libpng packages are available which fix a buffer overflow vulnerability. [Updated 06 Feb 2003] Added fixed packages for Advanced Workstation 2.1 The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. PNG is a bit-mapped graphics format similar to the GIF format. 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 a possible hacker creating a carefully crafted PNG file which could execute arbitrary code when the victim views it. Packages within Red Hat Linux Advanced Server, such as Mozilla, make use of the shared libpng library. All users are advised to upgrade to the errata packages, which contain libpng 1.0.14 with a backported patch that corrects this issue.
