(RHSA-2006:0015) initscripts security update

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 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 would be attempted on filesystems marked with _netdev in rc.sysinit
  before they were available.

Additionally, support for multi-core Itanium processors has been added to
redhat-support-check.

All users of initscripts should upgrade to these updated packages, which
contain backported patches to resolve these issues.
