Description

ssh 2.0.12, and possibly other versions, allows valid user names to attempt to enter the correct password multiple times, but only prompts an invalid user name for a password once, which allows remote attackers to determine user account names on the server.

Affected configurations

• ssh ssh2 2.0 • ssh ssh2 2.0.1 • ssh ssh2 2.0.2 • ssh ssh2 2.0.3 • ssh ssh2 2.0.4 • ssh ssh2 2.0.5 • ssh ssh2 2.0.6 • ssh ssh2 2.0.7 • ssh ssh2 2.0.8 • ssh ssh2 2.0.9 • ssh ssh2 2.0.10 • ssh ssh2 2.0.11 • ssh ssh2 2.0.12
