Vulnerability Assessment Details

USN144-1 : dbus vulnerability

Vulnerability Assessment Summary
dbus vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- dbus-1
- dbus-1-dev
- dbus-1-doc
- dbus-1-utils
- dbus-glib-1
- dbus-glib-1-dev
- python2.3-dbus

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
permited 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.

Solution :

Upgrade to :
- dbus-1-0.22-1ubuntu2.1 (Ubuntu 4.10)
- dbus-1-dev-0.22-1ubuntu2.1 (Ubuntu 4.10)
- dbus-1-doc-0.22-1ubuntu2.1 (Ubuntu 4.10)
- dbus-1-utils-0.22-1ubuntu2.1 (Ubuntu 4.10)
- dbus-glib-1-0.22-1ubuntu2.1 (Ubuntu 4.10)
- dbus-glib-1-dev-0.22-1ubuntu2.1 (Ubuntu 4.10)
- python2.3-dbus-0.22-1ubuntu2.1 (Ubuntu 4.10)
