    Harry Sintonen discovered that GNU tar does not properly handle member
    names containing '..', thus allowing an attacker to bypass the path
    names specified on the command line and replace files and directories in
    the target directory.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 1.27.1-2+deb8u1.
