RHSA-2012:1123 - Important: bind security update
Synopsis
Important: bind security update
Type/Severity
Security Advisory Important
Topic
Updated bind packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Description
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.
An uninitialized data structure use flaw was found in BIND when DNSSEC validation was enabled. A remote attacker able to send a large number of queries to a DNSSEC validating BIND resolver could use this flaw to cause it to exit unexpectedly with an assertion failure. (CVE-2012-3817)
Users of bind are advised to upgrade to these updated packages, which correct this issue. After installing the update, the BIND daemon (named) will be restarted automatically.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
