Test ID:1.3.6.1.4.1.25623.1.0.71221
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:0523
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2012:0523.

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
tEXt 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-2011-3048)

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

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
