Liebe Kolleginnen und Kollegen,

soeben erreichte uns nachfolgendes RedHat Security Advisory. Wir geben
diese Informationen unveraendert an Sie weiter.

CVE-2009-0798 – Schwachstelle in acpid

Durch eine Schwachstelle in acpid, einem Daemon fuer die Behandlung
von ACPI Events, werden geoeffnete UNIX Sockets nicht korrekt
geschlossen; acpid kann dabei in eine Endlosschleife geraten. Ein
entfernter Angreifer kann diese Schwachstelle ausnutzen, indem er eine
grosse Anzahl UNIX Sockets oeffnet und damit Verbindungsabbrueche
ausloest und CPU-Ressourcen aufzehrt.

Betroffen sind die folgenden Software Pakete und Plattformen:

Red Hat Security Advisory

Synopsis: Moderate: acpid security update
Advisory ID: RHSA-2009:0474-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0474.html
Issue date: 2009-05-07
CVE Names: CVE-2009-0798
=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

3. 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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):
