NVD Description

Note: Versions mentioned in the description apply only to the upstream openvpn package and not the openvpn package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Improper validation of source IP addresses in OpenVPN version 2.6.0 through 2.6.15 and 2.7_alpha1 through 2.7_rc1 allows an attacker to open a session from a different IP address which did not initiate the connection resulting in a denial of service for the originating client
