A certain Red Hat patch for acpid 1.0.4 effectively triggers a call to the open function with insufficient arguments, which might allow local users to leverage weak permissions on /var/log/acpid, and obtain sensitive information by reading this file, cause a denial of service by overwriting this file, or gain privileges by executing this file.

The remote OracleVM system is missing necessary patches to address critical security updates :

  - Resolves: #515062 CVE-2009-4033 acpid: log file created     with random permissions

  - start acpid before hal

  - Resolves: #503177

  - Updated the License entry

  - Fixed CVE-2009-0798 (too many open files DoS)

  - Resolves: #496292

From Red Hat Security Advisory 2009:1642 :

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.
