+From 5520704d075802df25ce4ffccc010ba1641bd484 Mon Sep 17 00:00:00 2001
+From: Nikos Mavrogiannopoulos <nmav@redhat.com>
+Date: Thu, 18 May 2017 18:03:34 +0200
+Subject: [PATCH] asn1_find_node: added safety check on asn1_find_node()
+
+This prevents a stack overflow in asn1_find_node() which
+is triggered by too long variable names in the definitions
+files. That means that applications have to deliberately
+pass a too long 'name' constant to asn1_write_value()
+and friends.  Reported by Jakub Jirasek.
