From: Meenali Gupta <[email protected]> A flaw was found in the SSH channel integrity.By manipulating sequence numbers during the handshake,an attacker can remove the initial messages on the secure channel without causing a MAC failure. For example,an attacker could disable the ping extension and thus disable the new countermeasure in OpenSSH 9.5 against keystroke timing attacks.
This CVE fix included function kex_proposal_populate_entries in kex.c file which is not present in 8.9p, so ignored this change.
