  <title>Apache JK Tomcat Connector: Remote execution of arbitrary code</title>
  <synopsis>
    The Apache Tomcat Connector (mod_jk) contains a buffer overflow
    vulnerability that could result in the remote execution of arbitrary code.
  </synopsis>

  <access>remote</access>
  <affected>
    <package name="www-apache/mod_jk" auto="yes" arch="*">
      <unaffected range="ge">1.2.21-r1</unaffected>
      <vulnerable range="lt">1.2.21-r1</vulnerable>
    </package>
  </affected>
  <background>
    <p>
    The Apache HTTP server is a very widely used web server. mod_jk
    provides the JK module for connecting Tomcat and Apache using the ajp13
    protocol.
    </p>
  </background>
  <description>
    <p>
    ZDI reported an unsafe memory copy in mod_jk that was discovered by an
    anonymous researcher in the map_uri_to_worker function of
    native/common/jk_uri_worker_map.c .
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker can send a long URL request to an Apache server using
    Tomcat. That can trigger the vulnerability and lead to a stack-based
    buffer overflow, which could result in the execution of arbitrary code
    with the permissions of the Apache user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Apache Tomcat users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-apache/mod_jk-1.2.21-r1&quot;</code>
  </resolution>
