Important: bind security update
Security Advisory: Important
Updated bind packages that fix one security issue are now available for
Red Hat Enterprise Linux 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.
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. DNS64 is
used to automatically generate DNS records so IPv6 based clients can access
IPv4 systems through a NAT64 server.
A flaw was found in the DNS64 implementation in BIND. If a remote attacker
sent a specially-crafted query to a named server, named could exit
unexpectedly with an assertion failure. Note that DNS64 support is not
enabled by default. (CVE-2012-5688)
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.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
