There is no fixed version for RHEL:7 openssh-askpass.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-askpass package and not the openssh-askpass package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
