RHEL 5 / 6 : bind (RHSA-2011:0926)

high Nessus Plugin ID 55539

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0926 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 requests. A remote attacker could use this flaw to send a specially-crafted DNS request packet to BIND, causing it to exit unexpectedly due to a failed assertion.
(CVE-2011-2464)

Users of bind97 on Red Hat Enterprise Linux 5, and bind on Red Hat Enterprise Linux 6, 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 bind package based on the guidance in RHSA-2011:0926.
