    Package        : bzip2
    Vulnerability  : race condition
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CAN-2005-0953
    Debian Bug     : 303300
    Imran Ghory discovered a race condition in bzip2, a high-quality
    block-sorting file compressor and decompressor.  When decompressing a
    file in a directory an attacker has access to, bunzip2 could be
    tricked to set the file permissions to a different file the user has
    permissions to.
    For the stable distribution (woody) this problem has been fixed in
    version 1.0.2-1.woody2
    For the testing distribution (sarge) this problem has been fixed in
    version 1.0.2-6.
    For the unstable distribution (sid) this problem has been fixed in
    version 1.0.2-6.
    We recommend that you upgrade your bzip2 packages.
