RHEL dbus security update


"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."

Systems should be updated with this patch when possible.
