Ubuntu 5.10 / 6.06 LTS / 6.10 : bind9 vulnerabilities (USN-418-1)

high Nessus Plugin ID 28010

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

A flaw was discovered in Bind's DNSSEC validation code. Remote attackers could send a specially crafted DNS query which would cause the Bind server to crash, resulting in a denial of service. Only servers configured to use DNSSEC extensions were vulnerable.

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

Solution

Update the affected packages.
