More information:

It was discovered that there was a potential denial of service vulnerability in strongswan, an IPsec VPN solution.

Strongswan could have queried URLs with untrusted certificates, and this could potentially lead to a DoS attack by blocking the fetcher thread.

For Debian 10 Buster, this problem has been fixed in version 5.7.2-1+deb10u3.

We recommend that you upgrade your strongswan packages.
