(Xvid: Array indexing vulnerabilities)

    Trixter Jack discovered an array indexing error in the
    get_intra_block() function in the file src/bitstream/mbcoding.c. The
    get_inter_block_h263() and get_inter_block_mpeg() functions in the same
    file were also reported as vulnerable.
  
Impact :

    An attacker could exploit these vulnerabilities to execute arbitrary
    code by tricking a user or automated system into processing a malicious
    video file with an application that makes use of the Xvid library.
  
Workaround :

    There is no known workaround at this time."
