Title: usbmuxd: User-assisted execution of arbitrary code (GLSA 201203-11)
Date: March 06, 2012
A buffer overflow vulnerability in usbmuxd could result in the
execution of arbitrary code.
usbmuxd is a USB multiplex daemon for use with Apple iPhone and iPod
Vulnerable: < 1.0.7-r1
Unaffected: >= 1.0.7-r1
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All usbmuxd users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-pda/usbmuxd-1.0.7-r1"
