The spnego_gss_accept_sec_context function in
lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.5 through
1.6.3, when SPNEGO is used, allows remote attackers to cause a denial of
service (NULL pointer dereference and daemon crash) via invalid
ContextFlags data in the reqFlags field in a negTokenInit token.
