    Teemu Salmela discovered a vulnerability in GNU tar that could allow a
    malicious user to overwrite arbitrary files by inducing the victim to
    attempt to extract a specially crafted tar file containing a
    GNUTYPE_NAMES record with a symbolic link.
    
    For the stable distribution (sarge), this problem has been fixed in
    version 1.14-2.3
    
    For the unstable distribution (sid) and the forthcoming stable release
    (etch), this problem will be fixed in version 1.16-2.
    
    We recommend that you upgrade your tar package.
