ntp bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

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.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
