Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : bind9 vulnerabilities (USN-888-1)

Medium Nessus Plugin ID 44106

Synopsis

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

Description

It was discovered that Bind would incorrectly cache bogus NXDOMAIN responses. When DNSSEC validation is in use, a remote attacker could exploit this to cause a denial of service, and possibly poison DNS caches. (CVE-2010-0097)

USN-865-1 provided updated Bind packages to fix a security vulnerability. The upstream security patch to fix CVE-2009-4022 was incomplete and CVE-2010-0290 was assigned to the issue. This update corrects the problem.

Michael Sinatra discovered that Bind did not correctly validate certain records added to its cache. When DNSSEC validation is in use, a remote attacker could exploit this to spoof DNS entries and poison DNS caches. Among other things, this could lead to misdirected email and web traffic.

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.
