Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-02-01 03:07:58 UTC 
CVE-2021-45079:

In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication.

Please stabilize 5.9.5.
