Scientific Linux Security Update : bind security for SL 4.x on i386/x86_64
medium Nessus Plugin ID 60629

Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
CVE-2009-0696 bind: DoS (assertion failure) via nsupdate packetsA 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 :
- when running on a system receiving a large number of (greater than 4,000) DNS requests per second, the named DNS nameserver became unresponsive, and the named service had to be restarted in order for it to continue serving requests. This was caused by a deadlock occurring between two threads that led to the inability of named to continue to service requests. This deadlock has been resolved with these updated packages so that named no longer becomes unresponsive under heavy load.
(BZ#512668)
After installing the update, the BIND daemon (named) will be restarted automatically.
Solution
