critical Nessus Plugin ID 66672
Language:
Synopsis
The remote web server is affected by multiple vulnerabilities.Description
According to its Server response header, the installed version of nginx is 1.1.4 through 1.2.8, 1.3.x, or 1.4.x prior to 1.4.1. It is, therefore, affected by multiple vulnerabilities :- A stack-based buffer overflow in 'ngx_http_parse.c' may allow a remote attacker to execute arbitrary code or trigger a denial of service condition via a specially crafted HTTP request. This vulnerability only affects versions greater than or equal to 1.3.9 and less than 1.4.1. (CVE-2013-2028)
- A memory disclosure vulnerability in 'ngx_http_parse.c' affects servers that use 'proxy_pass' to untrusted upstream servers. This issue can be triggered by a remote attacker via a specially crafted HTTP request.
Failed attempts may result in a denial of service condition. (CVE-2013-2070)
Solution
Either apply the patch manually or upgrade to nginx 1.4.1 / 1.5.0 or later.See Also
