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:
http://nginx.org/download/patch.2013.chunked.txt
As a temporary workaround the following configuration
can be used in each server{} block
if ($http_transfer_encoding ~* chunked) {
return 444;
}
UPDATE YOUR CPNGINX :
For updating the cPnginx run the following commands,
# /scripts/installnginx --version=1.4.1
UPDATE YOUR DANGINX :
For updating the Danginx please run the following command,
# /usr/local/directadmin/scripts/installnginx --version=1.4.1
