RHEL 5 RHSA-2010:0018-01 Moderate: Dbus Denial Of Service

Updated dbus packages that fix a security issue are now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team.. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: dbus security update Advisory ID: RHSA-2010:0018-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2010:0018.html Issue date: 2010-01-07 CVE Names: CVE-2009-1189 ==================================================================== 1. Summary: Updated dbus packages that fix a security issue are now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: D-Bus is a system for sending messages between applications. It is used for the system-wide message bus service and as a per-user-login-session messaging facility. It was discovered that the Red Hat Security Advisory RHSA-2009:0008 did not correctly fix the denial of service flaw in the system for sending messages between applications. A local user could use this flaw to send a message with a malformed signature to the bus, causing the bus (and, consequently, any process using libdbus to receive messages) to abort. (CVE-2009-1189) Note: Users running any application providing services over the system message bus are advised to test this update carefully before deploying it in production environments. All users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all running instances ofdbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted. 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 5. Bugs fixed (http://bugzilla.redhat.com/): 496672 - CVE-2009-1189 dbus: invalid fix for CVE-2008-3834 6.
