    Package        : libxml2
    Vulnerability  : computational denial of service
    Problem type   : local/remote
    Debian-specific: no
    Debug bug      : 660846
    CVE ID         : CVE-2012-0841
    
    It was discovered that the internal hashing routine of libxml2,
    a library providing an extensive API to handle XML data, is vulnerable to
    predictable hash collisions.  Given an attacker with knowledge of the
    hashing algorithm, it is possible to craft input that creates a large
    amount of collisions.  As a result it is possible to perform denial of
    service attacks against applications using libxml2 functionality because
    of the computational overhead.
    
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 2.7.8.dfsg-2+squeeze3.
    
    For the testing (wheezy) and unstable (sid) distributions, this problem
    will be fixed soon.
    
    We recommend that you upgrade your libxml2 packages.
