Description Julien Rische 2024-10-30 11:27:56 UTC
The Marvin attack affects the RSA protocol for PKINIT. This protocol is not used by default, we use FFDH or ECDH instead.

There might still be a use case to interoperate with Windows Server 2003. To be investigated.

This issue was prioritized due to this paper:
https://www.usenix.org/system/files/usenixsecurity24-shagam.pdf

Reproducible: Always
