    Package        : php5
    Vulnerability  : buffer overflow
    Problem type   : remote
    Debian-specific: no
    CVE ID         : CVE-2012-2386
    
    The Phar extension for PHP does not properly handle crafted tar files,
    leading to a heap-based buffer overflow.  PHP applications processing
    tar files could crash or, potentially, execute arbitrary code.
    
    In addition, this update addresses a regression which caused a crash
    when accessing a global object that is returned as $this from __get.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 5.3.3-7+squeeze13.
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid), this problem has been fixed in version 5.4.4~rc1-1.
    
    We recommend that you upgrade your php5 packages.
