1.2.1. RHBA-2010:0004: bug fix update
Note
This update has already been released (prior to the GA of this release) as errata RHBA-2010:0004
acpid is a daemon that dispatches ACPI (Advanced Configuration and Power Interface) events to user-space programs.
This updated acpid package fixes the following bug:
* the acpid package that was included with the Red Hat Enterprise Linux 5.4 update contained a package update script that returned a non-zero exit code when the the /var/log/acpid log file did not exist. However, if the acpid daemon had never been started on the system, and therefore /var/log/acpid did not exist, the faulty check caused the update process to fail, which could have resulted in two different acpid packages being installed on the same system and registered with the RPM database (rpmdb). This updated acpid package removes the spurious record from the rpmdb, thus resolving the problem. (BZ#548374)
All users of acpid are advised to upgrade to this updated package, which resolves this issue.
1.2.2. RHSA-2009:1642: Important security update
Important
This update has already been released (prior to the GA of this release) as the security errata RHSA-2009:1642
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.
