The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2011:0477 :
Updated gstreamer-plugins packages that fix two security issues are
now available for Red Hat Enterprise Linux 4.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
The gstreamer-plugins packages contain plug-ins used by the GStreamer
streaming-media framework to support a wide variety of media formats.
An integer overflow flaw, leading to a heap-based buffer overflow, and
a stack-based buffer overflow flaw were found in various ModPlug music
file format library (libmodplug) modules, embedded in GStreamer. An
attacker could create specially crafted music files that, when played
by a victim, would cause applications using GStreamer to crash or,
potentially, execute arbitrary code. (CVE-2006-4192, CVE-2011-1574)
All users of gstreamer-plugins are advised to upgrade to these updated
packages, which contain backported patches to correct these issues.
After installing the update, all applications using GStreamer (such as
Rhythmbox) must be restarted for the changes to take effect.
