    Several vulnerabilities have been identified in Gnash, the GNU Flash
    player.

    CVE-2012-1175

    Tielei Wang from Georgia Tech Information Security Center discovered a
    vulnerability in GNU Gnash which is caused due to an integer overflow
    error and can be exploited to cause a heap-based buffer overflow by
    tricking a user into opening a specially crafted SWF file.

    CVE-2011-4328

    Alexander Kurtz discovered an unsafe management of HTTP cookies. Cookie
    files are stored under /tmp and have predictable names, vulnerability
    that allows a local attacker to overwrite arbitrary files the users has
    write permissions for, and are also world-readable which may cause
    information leak.

    CVE-2010-4337

    Jakub Wilk discovered an unsafe management of temporary files during the
    build process. Files are stored under /tmp and have predictable names,
    vulnerability that allows a local attacker to overwrite arbitrary files
    the users has write permissions for.

    For the stable distribution (squeeze), this problem has been fixed in
    version 0.8.8-5+squeeze1.

    For the unstable distribution (sid), this problem has been fixed in
    version 0.8.10-5.

    We recommend that you upgrade your gnash packages.
