Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated acpid package that fixes one security issue is now
available for Red Hat Enterprise Linux 5.

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

acpid is a daemon that dispatches ACPI (Advanced Configuration and
Power Interface) events to user-space programs.

It was discovered that acpid could create its log file
('/var/log/acpid') with random permissions on some systems. A local
attacker could use this flaw to escalate their privileges if the log
file was created as world-writable and with the setuid or setgid bit
set. (CVE-2009-4033)

Please note that this flaw was due to a Red Hat-specific patch
(acpid-1.0.4-fd.patch) included in the Red Hat Enterprise Linux 5
acpid package.

Users are advised to upgrade to this updated package, which contains a
backported patch to correct this issue.
