Synopsis: Moderate: libpng security update
Issue Date: 2012-03-20
CVE Numbers: CVE-2011-3045

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 the way libpng processed
compressed chunks in PNG image files. An attacker could create a
specially-crafted PNG image file 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-2011-3045)

Users of libpng should upgrade to these updated packages, which correct
this issue. For Scientific Linux 5, they contain a backported
patch. For Scientific Linux 6, they upgrade libpng to version
1.2.48. All running applications using libpng must be restarted for the
update to take effect.
