Ubuntu 10.10 : bind9 vulnerability (USN-1070-1)

high Nessus Plugin ID 52164

Synopsis

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

Description

It was discovered that Bind incorrectly handled IXFR transfers and dynamic updates while under heavy load when used as an authoritative server. A remote attacker could use this flaw to cause Bind to stop responding, resulting in a denial of service.

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.
