Debian DSA-3473-1 : nginx - security update

high Nessus Plugin ID 88702

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities were discovered in the resolver in nginx, a small, powerful, scalable web/proxy server, leading to denial of service or, potentially, to arbitrary code execution. These only affect nginx if the 'resolver' directive is used in a configuration file.

Solution

Upgrade the nginx packages.

For the oldstable distribution (wheezy), these problems have been fixed in version 1.2.1-2.2+wheezy4.

For the stable distribution (jessie), these problems have been fixed in version 1.6.2-5+deb8u1.
