  <title>libxml2: Denial of Service</title>
  <synopsis>
    Multiple Denial of Services vulnerabilities were found in libxml2.

  <affected>
    <package name="dev-libs/libxml2" auto="yes" arch="*">
      <unaffected range="ge">2.7.3-r2</unaffected>

  <background>
    <p>
    libxml2 is a library to manipulate XML files.
    </p>
  </background>
  <description>
    <p>
    The following vulnerabilities were reported after a test with the
    Codenomicon XML fuzzing framework:
    </p>
    <ul>
    <li>
    Two use-after-free vulnerabilities are possible when parsing a XML file
    with Notation or Enumeration attribute types (CVE-2009-2416).
    </li>
    <li>
    A stack consumption vulnerability can be triggered via a large depth of
    element declarations in a DTD, related to a function recursion
    (CVE-2009-2414).
    </li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to open a
    specially crafted XML document with an application using libxml2
    resulting in a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libxml2 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libxml2-2.7.3-r2&quot;</code>
    <p>
    NOTE: This is a legacy GLSA. Updates for all affected architectures are
    available since August 30, 2009. It is likely that your system is
    already no longer affected by this issue.
    </p>
