Synopsis
Moderate: bind security update
Type/Severity
Security Advisory: Moderate
Topic
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.
Description
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
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
