The drv2.dll (aka RV20 decompression) module in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, RealPlayer Enterprise 2.1.2 and 2.1.3, Linux RealPlayer 11.0.2.1744, and possibly HelixPlayer 1.0.6 and other versions, allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted value of an unspecified length field in an RV20 video stream.

From Red Hat Security Advisory 2010:0981 :

Helix Player contains multiple security flaws and should no longer be used.  This update removes the HelixPlayer package from Red Hat Enterprise Linux 4. 

The Red Hat Security Response Team has rated this update as having critical 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.

Helix Player is a media player.

Multiple security flaws were discovered in RealPlayer. Helix Player and RealPlayer share a common source code base; therefore, some of the flaws discovered in RealPlayer may also affect Helix Player. Some of these flaws could, when opening, viewing, or playing a malicious media file or stream, lead to arbitrary code execution with the privileges of the user running Helix Player. (CVE-2010-2997, CVE-2010-4375, CVE-2010-4378, CVE-2010-4379, CVE-2010-4382, CVE-2010-4383, CVE-2010-4384, CVE-2010-4385, CVE-2010-4386, CVE-2010-4392)

The Red Hat Security Response Team is unable to properly determine the impact or fix all of these issues in Helix Player, due to the source code for RealPlayer being unavailable.

Due to the security concerns this update removes the HelixPlayer package from Red Hat Enterprise Linux 4. Users wishing to continue to use Helix Player should download it directly from https://player.helixcommunity.org/

Our removal packages have nothing in them but a README, so the HelixPlayer program will be removed from your SL 4 machine, but you will still have a package called HelixPlayer.

Note: Just to be clear. You will still have a package called HelixPlayer on your machine, but there will not be any program in it.
It will be an empty rpm.

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2010:0981 advisory.

  - HelixPlayer multiple flaws (CVE-2010-2997, CVE-2010-4375, CVE-2010-4378, CVE-2010-4379, CVE-2010-4382,     CVE-2010-4383, CVE-2010-4385, CVE-2010-4386, CVE-2010-4392, CVE-2010-4376) (CVE-2010-2997, CVE-2010-4375,     CVE-2010-4378, CVE-2010-4379, CVE-2010-4382, CVE-2010-4383, CVE-2010-4384, CVE-2010-4385, CVE-2010-4386,     CVE-2010-4392)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its build number, the installed version of RealPlayer on the remote Windows host is affected by multiple vulnerabilities:
