"If the end of an archive is reached while attempting to 'skip' past a
region of an archive, libarchive will enter an infinite loop wherein
it repeatedly attempts (and fails) to read further data. Impact : An
attacker able to cause a system to extract (via 'tar -x' or another
application which uses libarchive) or list the contents (via 'tar -t'
or another libarchive-using application) of an archive provided by the
attacker can cause libarchive to enter an infinite loop and use all
available CPU time. Workaround : No workaround is available."
