"The version of VLC media player installed on the remote host is
between 0.5.0 and 1.1.10.  As such, it is reportedly affected by
multiple vulnerabilities:

  - An integer overflow error exists in the handling of
    the RealAudio portions of RealMedia files. 
    (VideoLAN-SA-1105)

  - An integer underflow error exists in the handling of
    'strf' portions of AVI files. (VideoLAN-SA-1106)

Exploiting these vulnerabilities can lead to application crashes and
possibly code execution through heap-based buffer overflows.");
