A vulnerability has been found in nginx which may allow execution of arbitrary code.

Affected Packages

www-servers/nginx on all architectures
Affected versions < 1.4.7

Description

A bug in the SPDY implementation in nginx was found which might cause a heap memory buffer overflow in a worker process by using a specially crafted request. The SPDY implementation is not enabled in default configurations.

Impact

Workaround

Disable the spdy module in NGINX_MODULES_HTTP.
