Subject: [USN-705-1] NTP vulnerability
===========================================================
Ubuntu Security Notice USN-705-1 January 08, 2009
ntp vulnerability
CVE-2009-0021
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 7.10
Ubuntu 8.04 LTS
Ubuntu 8.10
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-refclock 1:4.2.0a+stable-8.1ubuntu6.1
ntp-simple 1:4.2.0a+stable-8.1ubuntu6.1
Ubuntu 7.10:
ntp 1:4.2.4p0+dfsg-1ubuntu2.1
Ubuntu 8.04 LTS:
ntp 1:4.2.4p4+dfsg-3ubuntu2.1
Ubuntu 8.10:
ntp 1:4.2.4p4+dfsg-6ubuntu2.2
In general, a standard system upgrade is sufficient to effect the
necessary changes.
Details follow:
It was discovered that NTP did not properly perform signature verification.
A remote attacker could exploit this to bypass certificate validation via
a malformed SSL/TLS signature.
Updated packages for Ubuntu 6.06 LTS:
