* Thu Apr 20 2023 Dmitry Belyavskiy <dbelyavs@redhat.com> - 8.7p1-30
|
||||
- Some non-terminating processes were listening on ports.
|
||||
Resolves: rhbz#2177768
|
||||
- On sshd startup, we check whether signing using the SHA1 for signing is
|
||||
available and don't use it when it isn't.
|
||||
- On ssh private key conversion we explicitly use SHA2 for testing RSA keys.
|
||||
- In sshd, when SHA1 signatures are unavailable, we fallback (fall forward :) )
|
||||
to SHA2 on host keys proof confirmation.
|
||||
- On a client side we permit SHA2-based proofs from server when requested SHA1
|
||||
proof (or didn't specify the hash algorithm that implies SHA1 on the client
|
||||
side). It is aligned with already present exception for RSA certificates.
|
||||
- We fallback to SHA2 if SHA1 signatures is not available on the client side
|
||||
(file sshconnect2.c).
|
||||
- We skip dss-related tests (they don't work without SHA1).
|
||||
Resolves: rhbz#2070163
|
||||
- FIPS compliance efforts for dh, ecdh and signing
|
||||
Resolves: rhbz#2091694
