nginx is a robust, small and high performance HTTP and reverse proxy
|

server.

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.

<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.
