Severity: normal

Date: June 22, 2014
Bug(s): #505018
ID: 201406-20

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.


Affected Packages

Package: www-servers/nginx
Vulnerable: < 1.4.7
Unaffected: >= 1.4.7
Architectures: All supported architectures


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.

Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.4.7"
