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.

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

  - An error in the 'Cook' codec initialization function     and can be used to access uninitialized memory.     (CVE-2010-0121)

  - Freed pointer access in the handling of the 'Stream     Title' tag in a SHOUTcast stream using the ICY protocol.
    (CVE-2010-2997)

  - An integer overflow error exists when handling a     malformed 'MLLT atom' in an AAC file. (CVE-2010-2999)

  - Heap-based buffer overflow when handling of multi-rate     audio streams. (CVE-2010-4375)

  - Heap-based buffer overflow when parsing GIF87a files     with large 'Screen Width' values in the 'Screen     Descriptor' header over RTSP. (CVE-2010-4376)

  - Heap-based buffer overflow when parsing of 'Cook' codec     information in a Real Audio file with many subbands.
    (CVE-2010-4377)

  - Memory corruption in parsing of a 'RV20' video stream.
    (CVE-2010-4378)

  - Heap-based buffer overflow when parsing 'AAC', 'IVR',     'RealMedia', 'RA5', 'RealPix', 'SIPR' and 'SOUND' files.
    (CVE-2010-0125, CVE-2010-4379, CVE-2010-4380,      CVE-2010-4381, CVE-2010-4382, CVE-2010-4383,      CVE-2010-4384, CVE-2010-4386, CVE-2010-4387,      CVE-2010-4390, CVE-2010-4391, CVE-2010-4392)

  - Integer overflow in the handling of frame dimensions in     a 'SIPR' stream. (CVE-2010-4385)

  - An input validation error in the 'pnen3260.dll' module     can allow arbitrary code execution via a crafted 'TIT2     atom' in an AAC file. (CVE-2010-4397)

  - Heap-based buffer overflow in the 'Cook' codec handling     functions. (CVE-2010-2579, CVE-2010-4389)

  - Heap-based buffer overflow in the decoding portion of     the 'Advanced Audio Coding' compression implementation.     (CVE-2010-4395)

  - Cross-site scripting in ActiveX control and several     HTML files. (CVE-2010-4396, CVE-2010-4388)

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.
