SecurityTracker Alert ID:  1015816
SecurityTracker URL:  http://securitytracker.com/id/1015816
CVE Reference:   CVE-2006-0323   (Links to External Site)
Date:  Mar 23 2006
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 10, 10.0.6, 10.5 (6.0.12.1040-1348)
Description:   A vulnerability was reported in RealPlayer. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create a specially crafted Macromedia Flash file (swf file) that, when loaded by the target user, will trigger a buffer overflow and execute arbitrary code on the target user's system. The code will run with the privileges of the target user.

RealOne Player v1 and v2, RealPlayer 8, RealPlayer Enterprise, and Rhapsody 3 (build 0.815 1.0.269) are also affected.

Impact:   A remote user can cause arbitrary code to be executed on the target user's system with the privileges of the target user.
Solution:   Red Hat has released a fix.

3. Problem description:

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

A buffer overflow bug was discovered in the way RealPlayer processes Flash
Media (.swf) files.  It is possible for a malformed Flash Media file to
execute arbitrary code as the user running RealPlayer.  The Common
Vulnerabilities and Exposures project assigned the name CVE-2006-0323 to
this issue.

All users of RealPlayer are advised to upgrade to this updated package,
which contains RealPlayer version 10.0.7 and is not vulnerable to this issue.

4. 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.
