CVE-2015-8023

The server implementation of the EAP-MSCHAPv2 protocol in the eap-mschapv2 plugin in strongSwan 4.2.12 through 5.x before 5.3.4 does not properly validate local state, which allows remote attackers to bypass authentication via an empty Success message in response to an initial Challenge message.

This issue did not affect the versions of strongimcv as shipped with Red Hat Enterprise Linux 7, as they did not include support for the eap-mschapv2 plugin.
