RHSA-2009:1642 - Important: acpid security update
Synopsis
Important: acpid security update
Type/Severity
Security Advisory Important
Topic
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.
Description
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.
Solution
Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
