A directory traversal vulnerability has been discovered in Archive::Tar.
Archive::Tar is a Perl module for creation and manipulation of tar files.
Jonathan Smith of rPath reported that Archive::Tar does not check for ".." in file names.
A remote attacker could entice a user or automated system to extract a specially crafted tar archive, overwriting files at arbitrary locations outside of the specified directory.
There is no known workaround at this time.
All Archive::Tar users should upgrade to the latest version:
