"An updated initscripts package that fixes a privilege escalation issue
and several bugs is now available.

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

The initscripts package contains the basic system scripts used to boot
your Red Hat system, change runlevels, and shut the system down
cleanly. Initscripts also contains the scripts that activate and
deactivate most network interfaces.

A bug was found in the way initscripts handled various environment
variables when the /sbin/service command is run. It is possible for a
local user with permissions to execute /sbin/service via sudo to
execute arbitrary commands as the 'root' user. The Common
Vulnerabilities and Exposures project (cve.mitre.org) assigned the
name CVE-2005-3629 to this issue.

The following issues have also been fixed in this update :

* extraneous characters were logged on bootup

* fsck was attempted on file systems marked with _netdev in rc.sysinit
before they were available

* the dynamically-linked /sbin/multipath was called instead of the
correct /sbin/multiplath.static

Additionally, this update includes support for partitioned multipath
devices and a technology preview of static IP over InifiniBand.

All users of initscripts should upgrade to this updated package, which
resolves these issues."
