[Full-disclosure] [USN-1070-1] Bind vulnerability

===========================================================
Ubuntu Security Notice USN-1070-1         February 23, 2011
bind9 vulnerability
CVE-2011-0414
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 10.10:
  libdns66                        1:9.7.1.dfsg.P2-2ubuntu0.2

In general, a standard system update will make all the necessary changes.

Details follow:

It was discovered that Bind incorrectly handled IXFR transfers and dynamic
updates while under heavy load when used as an authoritative server. A
remote attacker could use this flaw to cause Bind to stop responding,
resulting in a denial of service.
