The _gnutls_x509_verify_certificate function in lib/x509/verify.c in
libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the
last certificate is an arbitrary trusted, self-signed certificate, which
allows man-in-the-middle attackers to insert a spoofed certificate for any
Distinguished Name (DN).
