acpid security update

CentOS Errata and Security Advisory CESA-2009:1642

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.
