Security Advisory ntp security update

Advisory: RHSA-2006:0393-6
Type: Security Advisory
Severity: Low
Issued on: 2006-08-10
Last updated on: 2006-08-10
Affected Products: Red Hat Desktop (v. 4)
Red Hat Enterprise Linux AS (v. 4)
Red Hat Enterprise Linux ES (v. 4)
Red Hat Enterprise Linux WS (v. 4)
CVEs (cve.mitre.org): CVE-2005-2496

Details

Updated ntp packages that fix several bugs are now available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

The Network Time Protocol (NTP) is used to synchronize a computer's time
with a reference time source.

The NTP daemon (ntpd), when run with the -u option and using a string to
specify the group, uses the group ID of the user instead of the group,
which causes ntpd to run with different privileges than intended.
(CVE-2005-2496)

The following issues have also been addressed in this update:
- The init script had several problems
- The script executed on upgrade could fail
- The man page for ntpd indicated the wrong option for specifying a chroot
directory
- The ntp daemon could crash with the message "Exiting: No more memory!"
- There is a new option for syncing the hardware clock after a successful
run of ntpdate

Users of ntp should upgrade to these updated packages, which resolve these
issues.
