Synopsis

The remote Debian host is missing a security update.

Description

Hanno Böck from the Fuzzing Project discovered that incorrect validation of DNSSEC-signed records in the Bind DNS server could result in denial of service.

For Debian 6 'Squeeze', this issue has been fixed in bind9 version 1:9.7.3.dfsg-1~squeeze17. We recomend you to upgrade your bind9 packages.

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.
