Hi,
I am including a fix for wolfssl's CVE-2023-3724.
The vulnerability is tracked by the Security Team in #1041699 and is fixed in
unstable.
Aside from the changelog, this is exactly the same debdiff as provided by
5.5.4-2.1.
The new patch is taken from upstream as suggested by Jacob Barthelmeh.
Thanks,
Bastian
