"According to its build number, the installed version of RealPlayer on
the remote Windows host is earlier than 15.0.0.  As such, it is
affected by multiple vulnerabilities :

  - A head-based buffer overflow exists in the 'RealVideo'
    renderer. (CVE-2011-4244)

  - Memory corruption errors exist in the 'RealVideo'
    renderer and the 'AAC' codec. (CVE-2011-4245,
    CVE-2011-4246)

  - Remote code execution is possible due to errors related
    to 'QCELP' parsing. (CVE-2011-4247)

  - Remote code execution is possible due to errors related
    to 'AAC' file parsing. (CVE-2011-4248)

  - Remote code execution is possible due to errors related
    to improper handling of indexes in 'RV30' encoded files.
    (CVE-2011-4249)

  - Remote code execution is possible due to errors related
    to 'ATRC' file parsing. (CVE-2011-4250)

  - Remote code execution is possible due to errors related
    to 'RealAudio' 'Sample Size' parsing. (CVE-2011-4251)

  - Remote code execution is possible due to errors related
    to 'RV10' decoding. (CVE-2011-4252)

  - Remote code execution is possible due to errors related
    to 'RV20' decoding. (CVE-2011-4253) 

  - Remote code execution is possible due to errors related
    to 'RTSP' 'SETUP' requests (CVE-2011-4254)

  - Remote code execution is possible due to errors related
    to improper handling of invalid codec names. 
    (CVE-2011-4255)

  - Remote code execution is possible due to errors related
    to uninitialized indexes in 'RV30' files. 
    (CVE-2011-4256)

  - Remote code execution is possible due to errors related
    to 'Cook' codec channel parsing. (CVE-2011-4257)

  - Remote code execution is possible due to errors related
    to 'IVR MLTI' chunk length parsing. (CVE-2011-4258)

  - An integer underflow error exists related to 'MPG'
    width handling. (CVE-2011-4259)

  - Remote code execution is possible due to errors related
    to improper handling of malformed 'MP4' headers and 
    parsing of 'MP4' files in general.
    (CVE-2011-4260, CVE-2011-4262)

  - A heap corruption error exists related to improper
    handling of 'MP4' video dimensions. (CVE-2011-4261)");
