  <background>
    <p>
    udev is the device manager used in the Linux 2.6 kernel series.
    </p>

  <description>
    <p>
    Sebastian Krahmer of SUSE discovered the following two vulnerabilities:
    </p>
    <ul>
    <li>udev does not verify the origin of NETLINK messages
    properly (CVE-2009-1185).</li>
    <li>A buffer overflow exists in the
    util_path_encode() function in lib/libudev-util.c (CVE-2009-1186).</li>
    </ul>
  </description>
  <impact type="high">
    <p>
    A local attacker could gain root privileges by sending specially
    crafted NETLINK messages to udev or cause a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All udev users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sys-fs/udev-124-r2"</code>
  </resolution>
