    tar archives, a common format used for creating backups and
    distributing files on UNIX-like systems.

  <description>
    <p>
    Jim Meyering discovered a flaw in the handling of certain header
    fields that could result in a buffer overflow when extracting or
    listing the contents of an archive.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could construct a malicious tar archive that
    could potentially execute arbitrary code with the privileges of the
    user running GNU tar.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GNU tar users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/tar-1.15.1-r1&quot;</code>
  </resolution>
