CVE-2024-39894

A flaw was found in OpenSSH. A logic error in the SSH ObscureKeystrokeTiming feature on by default rendered this feature ineffective. A passive observer could still detect which network packets contained real keystrokes when the countermeasure was active because fake and real keystroke packets we...

CVE-2024-39894

OpenSSH versions 9.5 through 9.7 (prior to version 9.8) are vulnerable to timing attacks during keystroke entry. The root cause is a logic error in the ObscureKeystrokeTiming mechanism, which specifically affects echo-off password entries, such as those used for su and Sudo commands. An attacker ...
