gstreamer security update

CentOS Errata and Security Advisory CESA-2009:1123

GStreamer is a streaming media framework, based on graphs of filters which
operate on media data. GStreamer Good Plug-ins is a collection of
well-supported, good quality GStreamer plug-ins.

Multiple integer overflow flaws, that could lead to a buffer overflow, were
found in the GStreamer Good Plug-ins PNG decoding handler. An attacker
could create a specially-crafted PNG file that would cause an application
using the GStreamer Good Plug-ins library to crash or, potentially, execute
arbitrary code as the user running the application when parsed.
(CVE-2009-1932)

All users of gstreamer-plugins-good are advised to upgrade to these updated
packages, which contain a backported patch to correct these issues. After
installing the update, all applications using GStreamer Good Plug-ins (such
as some media playing applications) must be restarted for the changes to
take effect.
