  <affected>
    <package name="dev-util/xdelta" auto="yes" arch="*">
      <unaffected range="ge">3.0.10</unaffected>

  <background>
    <p>Xdelta is a C library and command-line tool for delta compression using
      VCDIFF/RFC 3284 streams.
    </p>
  </background>
  <description>
    <p>A buffer overflow can be triggered within xdelta when ran against a
      malicious input file.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could coerce the victim to run xdelta against a
      malicious input file. This may be leveraged by an attacker to crash
      xdelta and gain control of program execution.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All xdelta users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-util/xdelta-3.0.10"
    </code>
