Gentoo Linux Security Advisory GLSA 200909-18 - A buffer underflow vulnerability in the request URI processing of nginx might enable remote attackers to execute arbitrary code or cause a Denial of Service. 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. Versions less than 0.7.62 are affected.

Debian Security Advisory 1884-1 - Chris Ries discovered that nginx, a high-performance HTTP server, reverse proxy and IMAP/POP3 proxy server, is vulnerable to a buffer underflow when processing certain HTTP requests. An attacker can use this to execute arbitrary code with the rights of the worker process (www-data on Debian) or possibly perform denial of service attacks by repeatedly crashing worker processes via a specially crafted URL in an HTTP request.
