  <affected>
    <package name="app-arch/tar" auto="yes" arch="*">
      <unaffected range="ge">1.16-r2</unaffected>

  <background>
    <p>
    The Tar program provides the ability to create and manipulate tar
    archives.
    </p>
  </background>
  <description>
    <p>
    Tar does not properly extract archive elements using the GNUTYPE_NAMES
    record name, allowing files to be created at arbitrary locations using
    symlinks. Once a symlink is extracted, files after the symlink in the
    archive will be extracted to the destination of the symlink.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could entice a user to extract a specially crafted tar
    archive, possibly allowing for the overwriting of arbitrary files on
    the system extracting the archive.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Tar users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/tar-1.16-r2&quot;</code>
  </resolution>
