Greg MacManus, of iSIGHT Partners Labs, found a security problem
in several recent versions of nginx.  A stack-based buffer
overflow might occur in a worker process while handling a
specially crafted request, potentially resulting in arbitrary code
execution (CVE-2013-2028).

The problem affects nginx 1.3.9 - 1.4.0.

The problem is fixed in nginx 1.5.0, 1.4.1.

Patch for the problem can be found here:

As a temporary workaround the following configuration
can be used in each server{} block:

   if ($http_transfer_encoding ~* chunked) {
       return 444;
