RedHat: RHSA-2012-1122:01 Important: bind97 security update
Summary
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 bind97 are advised to upgrade to these updated packages, which
correct this issue. After installing the update, the BIND daemon (named)
will be restarted automatically.
Summary
