    Debian Bug     : 731860
    
    A directory traversal attack was reported against libtar, a C library for
    manipulating tar archives. The application does not validate the
    filenames inside the tar archive, allowing to extract files in arbitrary
    path. An attacker can craft a tar file to override files beyond the
    tar_extract_glob and tar_extract_all prefix parameter.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 1.2.11-6+deb6u2.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.2.16-1+deb7u2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.2.20-2.
    
    We recommend that you upgrade your libtar packages.
