1.33.1. RHSA-2010:0018: Moderate security update
Important
This update has already been released (prior to the GA of this release) as the security errata RHSA-2010:0018
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
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 of dbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted.
1.33.2. RHBA-2010:0236: bug fix update
Updated dbus packages that fix a multilib conflict that could cause installation failure on 64-bit architectures are now available.
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.
* the dbus api help files (installed to /usr/share/devhelp/books/dbus/api/ by default) included with the dbus-devel sub-package were previously automatically generated for each architecture. These auto-generated files contain different timestamps and internal links and, consequently, caused file conflicts with multilib that could prevent dbus-devel installation on 64-bit architectures. With this update, a pre-generated set of help files, dbus-1.1.2-pregen-doc-api-html.tar.bz2, has been added to the rpm. This removes the multilib file conflicts and allows installation of the dbus-devel sub-package in all circumstances. (BZ#471359)
All D-Bus users should install these updated packages which resolve this issue.
