Thomas Biege discovered a flaw in the privilege dropping of the NTP
server. When ntpd was configured to drop root privileges, and the
group to run under was specified as a name (as opposed to a numeric
group ID), ntpd changed to the wrong group. Depending on the actual
group it changed to, this could either cause non-minimal privileges,
or a malfunctioning ntp server if the group does not have the
privileges that ntpd actually needs.
On Ubuntu 4.10, ntpd does not use privilege dropping by default, so
you are only affected if you manually activated it. In Ubuntu 5.04,
privilege dropping is used by default, but this bug is already fixed.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected packages.
