Similarly, other timing attacks against keystroke entry could occur.", "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 were being sent unconditionally." ],
