RedHat: RHSA-2011-0845:01 Important: bind 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 off-by-one flaw was found in the way BIND processed negative responses
with large resource record sets (RRSets). An attacker able to send
recursive queries to a BIND server that is configured as a caching
resolver could use this flaw to cause named to exit with an assertion
failure. (CVE-2011-1910)
All BIND users are advised to upgrade to these updated packages, which
resolve this issue. After installing the update, the BIND daemon (named)
will be restarted automatically.
Summary
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
