Multiple security issues have been discovered in FastNetMon, a fast DDoS
analyzer: TLS connections were insufficently validated and malformed
Netflow/sFlow traffic could result in denial of service.

For the stable distribution (trixie), these problems have been fixed in

We recommend that you upgrade your fastnetmon packages.
