Open Source Vulnerability Database (OSVDB)
| Id | Description |
|---|---|
| 2140 | OpenSSH w/ PAM Username Validity Timing Attack OpenSSH portable contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when PAM is enabled; remote users can determine which usernames are valid by looking at the relative time it takes to receive an error response from the system. When PAM is enabled, OpenSSH returns an error almost immediately if a user does not exist, and is slower if the user exists but the password is incorrect. This disparity in timing will disclose when the attacker hits upon a valid username, making brute-force username/password guessing easier and resulting in a loss of confidentiality. |
