ISC BIND cache vulnerability

Vulnerability Note VU#706148

Original Release Date: 2010-12-01 | Last Revised: 2010-12-16

Overview

The ISC BIND nameserver contains a vulnerability that could allow a remote attacker to cause a denial of service.

Description

According to ISC:

Adding certain types of signed negative responses to cache doesn't clear any matching RRSIG records already in cache. A subsequent lookup of the cached data can cause named to crash (INSIST).

Impact

A remote attacker could cause the name server on an affected system to crash. ISC notes that this vulnerability affects recursive nameservers irrespective of whether DNSSEC validation is enabled or disabled.

Solution

Apply an update

Users who obtain BIND from a third-party vendor, such as their operating system vendor, should see the vendor information portion of this document for a partial list of affected vendors.

This vulnerability is addressed in ISC BIND versions 9.4-ESV-R4, 9.6.2-P3, 9.6-ESV-R3, and 9.7.2-P3. Users of BIND from the original source distribution should upgrade to one of these versions, as appropriate.
