Subject: [USN-867-1] Ntp vulnerability

===========================================================
Ubuntu Security Notice USN-867-1          December 08, 2009
ntp vulnerability
CVE-2009-3563
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 8.04 LTS
Ubuntu 8.10
Ubuntu 9.04
Ubuntu 9.10

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 6.06 LTS:
  ntp                             1:4.2.0a+stable-8.1ubuntu6.3
  ntp-server                      1:4.2.0a+stable-8.1ubuntu6.3

Ubuntu 8.04 LTS:
  ntp                             1:4.2.4p4+dfsg-3ubuntu2.3

Ubuntu 8.10:
  ntp                             1:4.2.4p4+dfsg-6ubuntu2.4

Ubuntu 9.04:
  ntp                             1:4.2.4p4+dfsg-7ubuntu5.2

Ubuntu 9.10:
  ntp                             1:4.2.4p6+dfsg-1ubuntu5.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Robin Park and Dmitri Vinokurov discovered a logic error in ntpd. A remote
attacker could send a crafted NTP mode 7 packet with a spoofed IP address
of an affected server and cause a denial of service via CPU and disk
resource consumption.
