USN-1354-1: usbmuxd vulnerability
1 February 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04

- usbmuxd - USB multiplexor daemon for iPhone and iPod Touch devices
It was discovered that usbmuxd did not correctly perform bounds checking when processing the SerialNumber field of USB devices. An attacker with physical access could use this to crash usbmuxd or potentially execute arbitrary code as the ‘usbmux’ user.
The problem can be corrected by updating your system to the following package versions:
