GLSA-200907-08 : Multiple Ralink wireless drivers: Execution of arbitrary code

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


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-200907-08
(Multiple Ralink wireless drivers: Execution of arbitrary code)

Aviv reported an integer overflow in multiple Ralink wireless card
drivers when processing a probe request packet with a long SSID,
possibly related to an integer signedness error.

Impact :

A physically proximate attacker could send specially crafted packets to
a user who has wireless networking enabled, possibly resulting in the
execution of arbitrary code with root privileges.

Workaround :

Unload the kernel modules.

Solution :

All external kernel modules have been masked and we recommend that
users unmerge those drivers. The Linux mainline kernel has equivalent
support for these devices and the vulnerability has been resolved in
stable versions of sys-kernel/gentoo-sources.
# emerge --unmerge 'net-wireless/rt2400'
# emerge --unmerge 'net-wireless/rt2500'
# emerge --unmerge 'net-wireless/rt2570'
# emerge --unmerge 'net-wireless/rt61'
# emerge --unmerge 'net-wireless/ralink-rt61'

Risk factor :

High / CVSS Base Score : 9.3
