RHSA-2007:0841 - Security Advisory

Topic

An updated RealPlayer package that fixes a security flaw is now available
for Red Hat Enterprise Linux 3 Extras, 4 Extras, and 5 Supplementary.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

RealPlayer is a media player that provides media playback locally and via
streaming.

A buffer overflow flaw was found in the way RealPlayer processed
Synchronized Multimedia Integration Language (SMIL) files. It was possible
for a malformed SMIL file to execute arbitrary code with the permissions of
the user running RealPlayer. (CVE-2007-3410)

All users of RealPlayer are advised to upgrade to this updated package
containing RealPlayer version 10.0.9 which is not vulnerable to this issue.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
