Detail
| Stephan Zeisberg discovered that the libreswan IPsec implementation could be forced into a crash/restart via a malformed IKEv1 Informational Exchange packet, resulting in denial of service. For the stable distribution (buster), this problem has been fixed in version 3.27-6+deb10u1. We recommend that you upgrade your libreswan packages. For the detailed security status of libreswan please refer to its security tracker page at: https://security-tracker.debian.org/tracker/libreswan |
