NDISwrapper: Arbitrary remote code execution

Background

NDISwrapper is a Linux kernel module that enables the use of Microsoft Windows drivers for wireless network devices.

Description

Anders Kaseorg reported multiple buffer overflows related to long ESSIDs.

Impact

A physically proximate attacker could send packets over a wireless network that might lead to the execution of arbitrary code with root privileges.

Workaround

There is no known workaround at this time.

Resolution

All NDISwrapper users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-wireless/ndiswrapper-1.53-r1"
