There's a serious vulnerability in NSS:

"An attacker could construct a PKCS 12 cert bundle in such a way that
could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes
being mishandled."

Apparently it is fixed in NSS, but they don't seem to say in which
version:

Help wanted to fix this bug!

That's been fixed by myself for nss-next
(246a3d90eac82966b691bdca4660ab9c5d802631) and by Tobias for nss itself,
via a graft to the latest 3.88.1 version
(b04ee227a47419291391a2b6e857e41ed1c32155).

Closing.

Thanks,
