Ubuntu 4.10 : dbus vulnerability (USN-144-1)

low Nessus Plugin ID 20537

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Besides providing the global system-wide communication bus, dbus also offers per-user 'session' buses which applications in an user's session can create and use to communicate with each other. Daniel Reed discovered that the default configuration of the session dbus allowed a local user to connect to another user's session bus if its address was known. The fixed packages restrict the default permissions to the user who owns the session dbus instance.

Please note that a standard Ubuntu installation does not use the session bus for anything, so this can only be exploited if you are using custom software which uses it.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
