nginx ngx_http_proxy_module.c Memory Disclosure

medium Nessus Plugin ID 66671

Language:

Synopsis

The remote web server is affected by a remote memory disclosure vulnerability.

Description

According to its Server response header, the installed version of nginx is 1.1.x, greater than or equal to 1.1.4, or 1.2.x prior to 1.2.9. It is, therefore, affected by a memory disclosure vulnerability in 'ngx_http_proxy_module.c' when 'proxy_pass' to untrusted upstream servers is used.

By sending a specially crafted request, an attacker may be able to gain access to worker process memory or trigger a denial of service condition.

Solution

Either apply the patch manually or upgrade to nginx 1.2.9 or later.
