(VLC: User-assisted execution of arbitrary code)

    Multiple vulnerabilities were found in VLC:
    Luigi Auriemma discovered that the stack-based buffer overflow when
    reading subtitles, which has been reported as CVE-2007-6681 in GLSA
    200803-13, was not properly fixed (CVE-2008-1881).
    Alin Rad Pop of Secunia reported an array indexing vulnerability in the
    sdpplin_parse() function when processing streams from RTSP servers in
    Xine code, which is also used in VLC (CVE-2008-0073).
    Drew Yao and Nico Golde reported an integer overflow in the
    MP4_ReadBox_rdrf() function in the file libmp4.c leading to a
    heap-based buffer overflow when reading MP4 files (CVE-2008-1489).
    Drew Yao also reported integer overflows in the MP4 demuxer,
    the Real demuxer and in the Cinepak codec, which might lead to buffer
    overflows (CVE-2008-1768).
    Drew Yao finally discovered and a
    boundary error in Cinepak, which might lead to memory corruption
    (CVE-2008-1769).
  
Impact :

    A remote attacker could entice a user to open a specially crafted media
    file or stream, possibly resulting in the remote execution of arbitrary
    code.
  
Workaround :

    There is no known workaround at this time."
