Mandriva Linux Security Update Advisory – Sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts. GSSAPI is only enabled in versions of openssh shipped in LE2005 and greater.
