RHEL 4 / 5 : bind (RHSA-2009:0020)

medium Nessus Plugin ID 35324

Synopsis

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

Description

The remote Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2009:0020 advisory.

BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols.

A flaw was discovered in the way BIND checked the return value of the OpenSSL DSA_do_verify function. On systems using DNSSEC, a malicious zone could present a malformed DSA certificate and bypass proper certificate validation, allowing spoofing attacks. (CVE-2009-0025)

For users of Red Hat Enterprise Linux 3 this update also addresses a bug which can cause BIND to occasionally exit with an assertion failure.

All BIND users are advised to upgrade to the updated package, which contains a backported patch to resolve this issue. After installing the update, BIND daemon 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-2009:0020.
