    Package        : libxfont
    CVE ID         : CVE-2014-0209 CVE-2014-0210 CVE-2014-0211
    
    Ilja van Sprundel of IOActive discovered several security issues in the
    X.Org libXfont library, which may allow a local, authenticated user to
    attempt to raise privileges; or a remote attacker who can control the
    font server to attempt to execute code with the privileges of the X
    server.
    
    CVE-2014-0209
    
        Integer overflow of allocations in font metadata file parsing could
        allow a local user who is already authenticated to the X server to
        overwrite other memory in the heap.
    
    CVE-2014-0210
    
        libxfont does not validate length fields when parsing xfs protocol
        replies allowing to write past the bounds of allocated memory when
        storing the returned data from the font server.
    
    CVE-2014-0211
    
        Integer overflows calculating memory needs for xfs replies could
        result in allocating too little memory and then writing the returned
        data from the font server past the end of the allocated buffer.
    
    For the oldstable distribution (squeeze), these problems have been fixed in
    version 1:1.4.1-5.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 1:1.4.5-4.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1:1.4.7-2.
    
    We recommend that you upgrade your libxfont packages.
