libimobiledevice vulnerability
==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10

Summary:

libimobiledevice could be made to overwrite files as the administrator, or
access device keys.

Software Description:
- libimobiledevice: Library for communicating with iPhone and iPod Touch devices

Details:

Paul Collins discovered that libimobiledevice incorrectly handled temporary
files. A local attacker could possibly use this issue to overwrite
arbitrary files and access device keys. In the default Ubuntu installation,
this issue should be mitigated by the Yama link restrictions.

Update instructions:

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

Ubuntu 13.04:
  libimobiledevice3               1.1.4-1ubuntu6.2

Ubuntu 12.10:
  libimobiledevice3               1.1.4-1ubuntu3.2

In general, a standard system update will make all the necessary changes.
