    <p>
    Squid is a full-featured Web proxy cache designed to run on Unix-like
    systems. It supports proxying and caching of HTTP, FTP, and other
    protocols, as well as SSL support, cache hierarchies, transparent
    caching, access control lists and many more features.
    </p>

  <description>
    <p>
    Certain malformed requests result in a segmentation fault in the
    sslConnectTimeout function, handling of other certain requests trigger
    assertion failures.
    </p>
  </description>
  <impact type="normal">
    <p>
    By performing malformed requests an attacker could cause Squid to crash
    by triggering an assertion failure or invalid memory reference.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Squid users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-proxy/squid-2.5.10-r2&quot;</code>
  </resolution>
