Description Ivan Nikolchev 2020-09-11 13:30:10 UTC

Description of problem:
1536bit group from RFC3526 is not allowed in FIPS mode according to 'SP800-56A rev 3'

NSS should not allow this group regardless of what DH-MIN is set in the policy.

Version-Release number of selected component (if applicable):

nss-3.53.1-11

How reproducible:
Always

Steps to Reproduce:
We have reproducer in /CoreOS/nss/Sanity/Well-known-DH-parameters

1. Run the test on rhel8 machine in fips mode, but before executing the test change DH-MIN to be lower than 1536 in the policy.


Actual results:
'Testing rfc3526-group-5-1536.pem' fails because the DH group is allowed and the connection is successful.


Expected results:
2. The DH group is not allowed and NSS aborts the connection.
