USN-2142-1: UDisks vulnerability

10 March 2014

UDisks could be made to crash or run programs as an administrator.



  • udisks - service to access and manipulate storage devices
  • udisks2 - service to access and manipulate storage devices


Florian Weimer discovered that UDisks incorrectly handled certain long path
names. A local attacker could use this issue to cause udisks to crash,
resulting in a denial of service, or possibly execute arbitrary code.
The default compiler options for affected releases should reduce the
vulnerability to a denial of service.

Update instructions

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

Ubuntu 13.10
Ubuntu 12.10
Ubuntu 12.04

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