Descriptions

http/modules/ngx_http_proxy_module.c in nginx 1.1.4 through 1.2.8 and 1.3.0 through 1.4.0, when proxy_pass is used with untrusted HTTP servers, allows remote attackers to cause a denial of service (crash) and obtain sensitive information from worker process memory via a crafted proxy response, a similar vulnerability to CVE-2013-2028.

http/modules/ngx_http_proxy_module.c en nginx v1.1.4 hasta v1.2.8 y v1.3.0 hasta v1.4.0, cuando proxy_pass es utilizado con servidores HTTP de no confianza, permite a atacantes remotos causar una denegación de servicio (caída) y obtener información sensible desde el proceso en memoria mediante una respuesta del proxy especialmente diseñada, una vulnerabilidad similar a CVE-2013-2028.

A buffer overflow has been identified in nginx, a small, powerful, scalable web/proxy server, when processing certain chunked transfer encoding requests if proxy_pass to untrusted upstream HTTP servers is used. An attacker may use this flaw to perform denial of service attacks, disclose worker process memory, or possibly execute arbitrary code.
