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.

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

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