Description

Updated libpng packages are available that fix a buffer overflow vulnerability.

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. Versions of libpng prior to 1.0.14 contain a buffer overflow in the progressive reader when the PNG datastream contains more IDAT data than indicated by the IHDR chunk. Such deliberately malformed datastreams would crash applications linked to libpng such as Mozilla that use the progressive reading feature. Packages within Red Hat Linux Advanced Server , such as Mozilla, make use of the shared libpng library, therefore all users are advised to upgrade to the errata packages which contain libpng 1.0.14. Libpng 1.0.14 is not vulnerable to this issue and contains fixes for other bugs including a number of memory leaks.
