advisory RHSA-2009:1181.

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.

A flaw was found in the way BIND handles dynamic update message packets
containing the ANY record type. A remote attacker could use this flaw to
send a specially-crafted dynamic update packet that could cause named to
exit with an assertion failure. (CVE-2009-0696)

Note: even if named is not configured for dynamic updates, receiving such
a specially-crafted dynamic update packet could still cause named to exit
unexpectedly.

This update also fixes the following bug:

  * the following message could have been logged: internal_accept: fcntl()
failed: Too many open files. With these updated packages, timeout queries
are aborted in order to reduce the number of open UDP sockets, and when the
accept() function returns an EMFILE error value, that situation is now
handled gracefully, thus resolving the issue. (BZ#498164)

All BIND users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues. After installing the
update, the BIND daemon (named) will be restarted automatically.");
