Debian DLA-295-1 : conntrack security update

medium Nessus Plugin ID 85547

Language:

Synopsis

The remote Debian host is missing a security update.

Description

'jann' discovered that in certain configurations, if the relevant conntrack kernel module is not loaded, conntrackd will crash when handling DCCP, SCTP or ICMPv6 packets. In the version found in Debian 6.0 'squeeze', this vulnerability only applies to ICMPv6.

For the oldoldstable distribution (squeeze), this problem has been fixed in version 1:0.9.14-2+deb6u1.

For the oldstable distribution (wheezy) and stable distribution (jessie), this problem will be fixed soon.

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 conntrack, and conntrackd packages.
