<package name="www-servers/lighttpd" auto="yes" arch="*">

<background>
<p>
lighttpd is a small-footprint, fast, compliant and very flexible
web-server which is optimized for high-performance environments.
</p>

<description>
<p>
lighttpd uses file extensions to determine which elements are programs
that should be executed and which are static pages that should be sent
as-is. By appending %00 to the filename, you can evade the extension
detection mechanism while still accessing the file.
</p>
</description>
<impact type="low">
<p>
A remote attacker could send specific queries and access the source of
scripts that should have been executed as CGI or FastCGI applications.
</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-1.3.10-r1&quot;</code>
</resolution>
