    Package        : php5
    Vulnerability  : denial of service
    CVE ID         : CVE-2014-1943
    Debian Bug     : 739012
    
    It was discovered that file, a file type classification tool, contains a
    flaw in the handling of "indirect" magic rules in the libmagic library,
    which leads to an infinite recursion when trying to determine the file
    type of certain files. The Common Vulnerabilities and Exposures project
    ID CVE-2014-1943 has been assigned to identify this flaw. Additionally,
    other well-crafted files might result in long computation times (while
    using 100% CPU) and overlong results.
    
    This update corrects this flaw in the copy that is embedded in the
    php5 package.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 5.3.3-7+squeeze19.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 5.4.4-14+deb7u8.
    
    For the testing distribution (jessie) and the unstable distribution
    (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your php5 packages.
