RHSA-2009:0474 - Moderate: acpid security update
Synopsis
Moderate: acpid security update
Type/Severity
Security Advisory Moderate
Topic
An updated acpid package that fixes one security issue is now available for Red Hat Enterprise Linux 2.1, 3, 4, and 5.
This update has been rated as having moderate 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.
Anthony de Almeida Lopes of Outpost24 AB reported a denial of service flaw in the acpid daemon's error handling. If an attacker could exhaust the sockets open to acpid, the daemon would enter an infinite loop, consuming most CPU resources and preventing acpid from communicating with legitimate processes. (CVE-2009-0798)
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.
