    <p>
    CVS (Concurrent Versions System) is an open-source network-transparent
    version control system. It contains both a client utility and a server.

    <p>
    Alen Zukich has discovered several serious security issues in CVS,
    including at least one buffer overflow (CAN-2005-0753), memory leaks
    and a NULL pointer dereferencing error. Furthermore when launching
    trigger scripts CVS includes a user controlled directory.
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker could exploit these vulnerabilities to cause a Denial of
    Service or execute arbitrary code with the permissions of the CVS
    pserver or the authenticated user (depending on the connection method
    used).
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All CVS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-util/cvs-1.11.20"</code>
  </resolution>
