RHEL 2.1 / 3 / 4 / 5 : bind (RHSA-2009:0020)

Medium Nessus Plugin ID 35324

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated Bind packages to correct a security issue are now available for Red Hat Enterprise Linux 2.1, 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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.

Solution

Update the affected packages.
