<background>
<p>
nginx is a robust, small and high performance HTTP and reverse proxy
server.

<description>
<p>
Chris Ries reported a heap-based buffer underflow in the
ngx_http_parse_complex_uri() function in http/ngx_http_parse.c when
parsing the request URI.
</p>
</description>
<impact type="high">
<p>
A remote attacker might send a specially crafted request URI to a nginx
server, possibly resulting in the remote execution of arbitrary code
with the privileges of the user running the server, or a Denial of
Service. NOTE: By default, nginx runs as the "nginx" user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All nginx 0.5.x users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/nginx-0.5.38&quot;</code>
<p>
All nginx 0.6.x users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/nginx-0.6.39&quot;</code>
<p>
All nginx 0.7.x users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/nginx-0.7.62&quot;</code>
