Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201203-11
(usbmuxd: User-assisted execution of arbitrary code)

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.
