Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : bind9 vulnerability (USN-3769-1)

Medium Nessus Plugin ID 117630

Synopsis

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

Description

It was discovered that Bind incorrectly handled the deny-answer-aliases feature. If this feature is enabled, a remote attacker could 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.
