vuxml

0.8 is vulerable to:

CVE-2025-59529 - simple protocol server ignores the documented client limit and
accepts unlimited connections, allowing for easy local DoS

For more information please read:

However, `0.9` has not been released yet, and the only patched version is
`0.9-rc2`.

The patch could be cherry picked and applied to the port, however due to this
being a moderate cve which is local-only, and is a denial of service, it really
doesn't seem to be a big deal.

Nethertheless, I have created an issue to track this. I have also attached a
vuxml for the CVE.
