Debian DLA-404-1 : nginx security update

medium Nessus Plugin ID 88422

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a invalid pointer deference in nginx, a small, powerful, scalable web/proxy server. An invalid pointer dereference might occur during DNS server response processing, allowing an attacker who is able to forge UDP packets from the DNS server to cause worker process crash

For Debian 6 Squeeze, this issue has been fixed in nginx version 0.7.67-3+squeeze4+deb6u1.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected nginx, and nginx-dbg packages.
