Ubuntu 12.04 LTS / 12.10 : bind9 vulnerability (USN-1657-1)

High Nessus Plugin ID 63184


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


It was discovered that Bind incorrectly handled certain crafted queries when DNS64 was enabled. A remote attacker could use this flaw 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.


Update the affected bind9 package.
