Synopsis
========

A buffer overflow vulnerability in usbmuxd could result in the
execution of arbitrary code.

Background
==========

usbmuxd is a USB multiplex daemon for use with Apple iPhone and iPod
Touch devices.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-pda/usbmuxd             < 1.0.7-r1               >= 1.0.7-r1

Description
===========

The "receive_packet()" function in libusbmuxd.c contains a boundary
error when parsing the "SerialNumber" field of a USB device, which
could cause a heap-based buffer overflow.

Impact
======

An attacker could gain physical access or entice a user to connect to a
malicious USB device, possibly resulting in execution of arbitrary code
with the privileges of the "usbmux" user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All usbmuxd users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-pda/usbmuxd-1.0.7-r1"
