pkcs7: Prevent NULL pointer dereference, since sinfo is not always set.
The ASN.1 parser does not necessarily set the sinfo field, this patch prevents a NULL pointer dereference on broken input. Fixes: 99db44350672 ("PKCS#7: Appropriately restrict authenticated attributes and content type") Signed-off-by: Eric Sesterhenn <eric.sesterhenn@x41-dsec.de> Signed-off-by: David Howells <dhowells@redhat.com> cc: stable@vger.kernel.org # 4.3+
