Description

The libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

A heap-based buffer overflow flaw was found in libpng. An attacker could create a specially crafted PNG image that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3026)

Users of libpng and libpng10 should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libpng or libpng10 must be restarted for the update to take effect.
