[USN-777-1] Ntp vulnerabilities



===========================================================
Ubuntu Security Notice USN-777-1               May 19, 2009
ntp vulnerabilities
CVE-2009-0159, CVE-2009-1252
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 8.04 LTS
Ubuntu 8.10
Ubuntu 9.04

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-8.1ubuntu6.2
  ntp-server                      1:4.2.0a+stable-8.1ubuntu6.2

Ubuntu 8.04 LTS:
  ntp                             1:4.2.4p4+dfsg-3ubuntu2.2

Ubuntu 8.10:
  ntp                             1:4.2.4p4+dfsg-6ubuntu2.3

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

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

Details follow:

A stack-based buffer overflow was discovered in ntpq. If a user were
tricked into connecting to a malicious ntp server, a remote attacker could
cause a denial of service in ntpq, or possibly execute arbitrary code with
the privileges of the user invoking the program. (CVE-2009-0159)

Chris Ries discovered a stack-based overflow in ntp. If ntp was configured
to use autokey, a remote attacker could send a crafted packet to cause a
denial of service, or possible execute arbitrary code. (CVE-2009-1252)
