Debian DLA-285-1 : bind9 security update

High Nessus Plugin ID 85052

Synopsis

The remote Debian host is missing a security update.

Description

Jonathan Foote discovered that the BIND DNS server does not properly handle TKEY queries. A remote attacker can take advantage of this flaw to mount a denial of service via a specially crafted query triggering an assertion failure and causing BIND to exit.

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 packages.
