    <p>
    The Oulu University discovered that bzip2 does not properly check
    offsets provided by the bzip2 file, leading to a buffer overread.
    </p>
  </description>
  <impact type="normal">
    <p>
    Remote attackers can entice a user or automated system to open a
    specially crafted file that triggers a buffer overread, causing a
    Denial of Service. libbz2 and programs linking against it are also
    affected.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All bzip2 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/bzip2-1.0.5&quot;</code>
