>Description:
When passing GSS_C_NO_OID to gss_init_sec_context as the mech_type argument libgssapi will segfault in _gss_oid_equal(gss_utils.c:39). The manpage states that:
mech_type Object ID of desired mechanism. Supply GSS_C_NO_OID to
obtain an implementation specific default
So sending in GSS_C_NO_OID as mech_type should be allowed.
>How-To-Repeat:
Issue a gss_init_sec_context() call with the mech_type argument being GSS_C_NO_OID. Then wait for the segfault.
