Detail

Synopsis

Multiple vulnerabilities have been found in nginx, the worst of which may allow execution of arbitrary code.

Background

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

Description

Multiple vulnerabilities have been discovered in nginx. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker could send a specially crafted request, possibly resulting in execution of arbitrary code with the privileges of the process, or a Denial of Service condition. Furthermore, a context-dependent attacker may be able to obtain sensitive information.

Workaround

There is no known workaround at this time.

Resolution

All nginx users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/nginx-1.4.1-r2"
