CVEs (cve.mitre.org): CVE-2009-0798

Details

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.

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
