Package        : strongswan
Version        : 5.7.2-1+deb10u3
CVE ID         : CVE-2022-40617
Debian Bug     : #1021271

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.
