Hi,

Colin, this is just to fill a bug for BTS tracking, I'm aware that you
know, and we agreed to just fix it along when updating to 9.8.

The following vulnerability was published for openssh.

CVE-2024-39894[0]:
| OpenSSH 9.5 through 9.7 before 9.8 sometimes allows timing attacks
| against echo-off password entry (e.g., for su and Sudo) because of
| an ObscureKeystrokeTiming logic error. Similarly, other timing
| attacks against keystroke entry could occur.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
