Test ID:
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0018
The remote host is missing updates announced in
advisory RHSA-2010:0018.

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.

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.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
