udisks, udisks2 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

UDisks could be made to manipulate directories as the administrator.

Software Description:
- udisks: service to access and manipulate storage devices
- udisks2: service to access and manipulate storage devices

Details:

Florian Weimer discovered that UDisks incorrectly handled certain long path
names. A local attacker could use this issue to cause udisks to create
certain directory structures, possibly leading to privilege escalation.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
udisks 1.0.4-8ubuntu1.1
udisks2 2.1.0-4ubuntu0.1

Ubuntu 12.10:
udisks 1.0.4-6ubuntu0.1
udisks2 2.0.0-1ubuntu1.1

Ubuntu 12.04 LTS:
udisks 1.0.4-5ubuntu2.2

After a standard system update you need to reboot your computer to make all
the necessary changes.
