Debian LTS: DLA-3143-1: strongswan security update
Summary
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.
For the detailed security status of strongswan please refer to
