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 .
