Gentoo Linux Security Advisory

Title: usbmuxd: User-assisted execution of arbitrary code (GLSA 201203-11)
Severity: normal
Exploitable: local
Date: March 06, 2012
Bug(s): #399409
ID: 201203-11

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: app-pda/usbmuxd
Vulnerable: < 1.0.7-r1
Unaffected: >= 1.0.7-r1
Architectures: All supported architectures


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