RedHat Security Advisory RHSA-2009:1642

The remote host is missing updates announced in advisory RHSA-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.
