DEBIAN-CVE-2003-1562
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password...

unix entropy source can be used for keystroke timing attacks
Another bizarre vulnerability, for your amusement... Several unix systems systems provide a secure entropy source maintained by collecting certain information that is supposed to be practically unpredictable such as interrupt timings, keyboard scancodes or device request times, then running it th...

OpenSSH w/ PAM Multiple Timing Attack Weaknesses
The remote host seems to be running an SSH server that could allow an attacker to determine the existence of a given login by comparing the time the remote sshd daemon takes to refuse a bad password for a nonexistent login compared to the time it takes to refuse a bad password for a valid login. ...

CVE-2003-0190
CVE-2003-0190 affects OpenSSH-portable/OpenSSH 3.6.1p1 and earlier with PAM enabled. The vulnerability is a timing side‑channel: when a login attempts with a non-existent username, an error is returned immediately, allowing remote attackers to determine valid usernames. This is an information dis...

security flaw
OpenSSL does not use RSA blinding by default, which allows local and remote attackers to obtain the server's private key by determining factors using timing differences on 1 the number of extra reductions during Montgomery reduction, and 2 the use of different integer multiplication algorithms...
