Package : strongswan
Version : 5.5.1-4+deb9u6
CVE ID : CVE-2021-45079

Zhuowei Zhang discovered a bug in the EAP authentication client code
of strongSwan, an IKE/IPsec suite, that may allow to bypass the client
and in some scenarios even the server authentication, or could lead to
a denial-of-service attack.

For Debian 9 stretch, this problem has been fixed in version
5.5.1-4+deb9u6.

We recommend that you upgrade your strongswan packages.
