(FFmpeg: Multiple vulnerabilities)

    Multiple vulnerabilities were found in FFmpeg:
    astrange
    reported a stack-based buffer overflow in the str_read_packet() in
    libavformat/psxstr.c when processing .str files (CVE-2008-3162).
    Multiple buffer overflows in libavformat/utils.c
    (CVE-2008-4866).
    A buffer overflow in libavcodec/dca.c
    (CVE-2008-4867).
    An unspecified vulnerability in the
    avcodec_close() function in libavcodec/utils.c (CVE-2008-4868).
    Unspecified memory leaks (CVE-2008-4869).
    Tobias Klein
    repoerted a NULL pointer dereference due to an integer signedness error
    in the fourxm_read_header() function in libavformat/4xm.c
    (CVE-2009-0385).
  
Impact :

    A remote attacker could entice a user to open a specially crafted media
    file, possibly leading to the execution of arbitrary code with the
    privileges of the user running the application, or a Denial of Service.
  
Workaround :

    There is no known workaround at this time."
