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"
