Detail

Synopsis

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

Background

nginx is a robust, small, and high performance HTTP and reverse proxy server.

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

A remote attacker could cause execution of arbitrary code by using a specially crafted request.

Workaround

Disable the spdy module in NGINX_MODULES_HTTP.

Resolution

All nginx users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/nginx-1.4.7"
