An updated RealPlayer package that fixes a buffer overflow bug is now available for Red Hat Enterprise Linux Extras 3 and 4.

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

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.

According to its version number, the installed version of Rhapsody on the remote host suffers from a buffer overflow involving SWF files. To exploit this issue, a remote attacker needs to convince a user to attempt to play a maliciously crafted SWF file using the affected application.

Secunia Advisories Reports :

A boundary error when processing SWF files can be exploited to cause a buffer overflow. This may allow execution of arbitrary code on the user's system.

According to its build number, the installed version of RealPlayer / RealOne Player / RealPlayer Enterprise on the remote Windows host suffers from one or more buffer overflows involving maliciously- crafted SWF and MBC files as well as web pages.  In addition, it also may be affected by a local privilege escalation issue.

The remote host is affected by the vulnerability described in GLSA-200603-24 (RealPlayer: Buffer overflow vulnerability)

    RealPlayer is vulnerable to a buffer overflow when processing     malicious SWF files.
  Impact :

    By enticing a user to open a specially crafted SWF file an     attacker could execute arbitrary code with the permissions of the user     running the application.
  Workaround :

    There is no known workaround at this time.

The installed version of RealPlayer / RealOne Player / RealPlayer Enterprise for Windows on the remote host is prone to buffer overflow and heap overflow vulnerabilities.  An attacker may be able to leverage these issues to execute arbitrary code on the remote host subject to the permissions of the user running the affected application.  Note that a user doesn't necessarily need to explicitly access a malicious media file since the browser may automatically pass RealPlayer skin files (ie, files with the extension '.rjs') to the application.

According to its banner, the version of iTunes for Windows on the remote host launches a helper application by searching for it through various system paths.  An attacker with local access can leverage this issue to place a malicious program in a system path and have it called before the helper application.
