Bug Fix Advisory ntp bug fix update

Advisory: RHBA-2011:1454-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2011-11-16
Last updated on: 2011-11-16
Affected Products: Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux Desktop (v. 5 client)

Details

An updated ntp package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

The Network Time Protocol (NTP) is used to synchronize a computer's time with
another referenced time source. This package includes the ntpd daemon which
continuously adjusts system time and utilities used to query and configure the
ntpd daemon.

This update fixes the following bug:

* The ntp-keygen utility always used the DES-CBC (Data Encryption
Standard-Cipher Block Chaining) encryption algorithm to encrypt private NTP
keys. This algorithm is not supported in FIPS (Federal Information Processing
Standard) mode. As a consequence, ntp-keygen generated empty private keys when
it was used on systems with FIPS mode enabled. To solve this problem, a new "-C"
option has been added for ntp-keygen that allows for selection of an encryption
algorithm for private key files. Private NTP keys are now generated as expected
on systems with FIPS mode enabled. (BZ#449750)

All users of ntp are advised to upgrade to this updated package, which fixes
this bug.
