<background>
<p>
Lighttpd is a lightweight HTTP web server.

<description>
<p>
Stefan Esser discovered errors with evidence of memory corruption in
the code parsing the headers. Several independent researchers also
reported errors involving the handling of HTTP headers, the mod_auth
and mod_scgi modules, and the limitation of active connections.
</p>
</description>
<impact type="normal">
<p>
A remote attacker can trigger any of these vulnerabilities by sending
malicious data to the server, which may lead to a crash or memory
exhaustion, and potentially the execution of arbitrary code.
Additionally, access-deny settings can be evaded by appending a final /
to a URL.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Lighttpd users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/lighttpd-1.4.16&quot;</code>
</resolution>
