DESCRIPTION:
rigan has reported a vulnerability in usbmuxd, which potentially can
be exploited by malicious people with physical access to compromise a
vulnerable system.

The vulnerability is caused due to a boundary error within the
"receive_packet()" function (libusbmuxd/libusbmuxd.c) when processing
a property list containing an overly long "SerialNumber" field, which
can be exploited to cause a heap-based buffer overflow.

Successful exploitation may allow the execution of arbitrary code,
but requires that the attacker is able to connect a malicious USB
device.

SOLUTION:
Fixed in the GIT repository.
