Ubuntu Security Notice - bind9 vulnerability (USN-1783-1)
==========================================================================
Ubuntu Security Notice USN-1783-1
March 29, 2013

bind9 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

Bind could be made to consume memory or crash if it received specially
crafted network traffic.

Software Description:
- bind9: Internet Domain Name Server

Details:

Matthew Horsfall discovered that Bind incorrectly handled regular
expression checking. A remote attacker could use this flaw to cause Bind to
consume an excessive amount of memory, possibly resulting in a denial of
service. This issue was corrected by disabling RDATA regular expression
syntax checking.

Update instructions:

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

Ubuntu 12.10:
  bind9                           1:9.8.1.dfsg.P1-4.2ubuntu3.2
  libdns81                        1:9.8.1.dfsg.P1-4.2ubuntu3.2

Ubuntu 12.04 LTS:
  bind9                           1:9.8.1.dfsg.P1-4ubuntu0.6
  libdns81                        1:9.8.1.dfsg.P1-4ubuntu0.6

Ubuntu 11.10:
  bind9                           1:9.7.3.dfsg-1ubuntu4.6
  libdns69                        1:9.7.3.dfsg-1ubuntu4.6

Ubuntu 10.04 LTS:
  bind9                           1:9.7.0.dfsg.P1-1ubuntu0.9
  libdns64                        1:9.7.0.dfsg.P1-1ubuntu0.9
