Ubuntu 12.04 LTS / 14.04 LTS / 16.04 LTS / 16.10 : bind9 vulnerability (USN-3119-1)

Medium Nessus Plugin ID 94468

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Tony Finch and Marco Davids discovered that Bind incorrectly handled certain responses containing a DNAME answer. A remote attacker could possibly use this issue to cause Bind to crash, 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 bind9 package.
