Description

Background

OpenVPN is a multi-platform, full-featured SSL VPN solution.

Description

OpenVPN does not properly handle control channel packets that are too small.

Impact

A remote authenticated attacker could send a specially crafted control channel packet, possibly resulting in a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All OpenVPN users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-misc/openvpn-2.3.6"
