pixman security update

CentOS Errata and Security Advisory CESA-2013:1869

Pixman is a pixel manipulation library for the X Window System and Cairo.

An integer overflow, which led to a heap-based buffer overflow, was found
in the way pixman handled trapezoids. If a remote attacker could trick an
application using pixman into rendering a trapezoid shape with specially
crafted coordinates, it could cause the application to crash or, possibly,
execute arbitrary code with the privileges of the user running the
application. (CVE-2013-6425)

Users are advised to upgrade to these updated packages, which contain a
backported patch to correct this issue. All applications using pixman
must be restarted for this update to take effect.
