RHEL 5 : bind97 (RHSA-2011:1459)

high Nessus Plugin ID 56867

Synopsis

The remote Red Hat host is missing a security update for bind97.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:1459 advisory.

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

A flaw was discovered in the way BIND handled certain DNS queries, which caused it to cache an invalid record. A remote attacker could use this flaw to send repeated queries for this invalid record, causing the resolvers to exit unexpectedly due to a failed assertion. (CVE-2011-4313)

Users of bind97 are advised to upgrade to these updated packages, which resolve this issue. After installing the update, the BIND daemon (named) will be restarted automatically.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL bind97 package based on the guidance in RHSA-2011:1459.
