    Tobias Klein reported the following vulnerabilities:
    A
    stack-based buffer overflow when processing CUE image files in
    modules/access/vcd/cdrom.c (CVE-2008-5032).
    A stack-based
    buffer overflow when processing RealText (.rt) subtitle files in the
    ParseRealText() function in modules/demux/subtitle.c
    (CVE-2008-5036).
    An integer overflow when processing RealMedia
    (.rm) files in the ReadRealIndex() function in real.c in the Real
    demuxer plugin, leading to a heap-based buffer overflow
    (CVE-2008-5276).
  
Impact :

    A remote attacker could entice a user to open a specially crafted CUE
    image file, RealMedia file or RealText subtitle file, possibly
    resulting in the execution of arbitrary code with the privileges of the
    user running the application.
  
Workaround :

    There is no known workaround at this time."
