    UnAce is an utility to extract, view and test the contents of an
    ACE archive.

  <description>
    <p>
    Ulf Harnhammar discovered that UnAce suffers from buffer overflows
    when testing, unpacking or listing specially crafted ACE archives
    (CAN-2005-0160). He also found out that UnAce is vulnerable to
    directory traversal attacks, if an archive contains "./.." sequences or
    absolute filenames (CAN-2005-0161).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could exploit the buffer overflows to execute
    malicious code or the directory traversals to overwrite arbitrary
    files.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All UnAce users should upgrade to the latest available 1.2
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/unace-1.2b-r1&quot;</code>
  </resolution>
