Description:
Two security issues have been reported in OpenSSH, which can be exploited malicious users to gain escalated privileges or bypass certain security restrictions.
1) An error in handling dynamic port forwardings when no listen address is specified, can cause "GatewayPorts" to be incorrectly activated.
The security issue is reportedly introduced in version 4.0.
2) An error in handling GSSAPI credential delegation can allow a user, who did not login using GSSAPI authentication, to be delegated with GSSAPI credentials.
Successful exploitation requires that "GSSAPIDelegateCredentials" is enabled.
Solution:
Update to version 4.2p1.
