high Nessus Plugin ID 131225

Language:

Synopsis

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

Description

It was discovered that Bind incorrectly handled certain TCP-pipelined queries. A remote attacker could possibly use this issue to cause Bind to consume resources, 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.
