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

high Nessus Plugin ID 39779

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'
