[3.6] libtasn1: asn1_find_node() based stackoverflow (CVE-2017-6891)
Two errors in the “asn1_find_node()” function (lib/parser_aux.c)
within GnuTLS libtasn1 version 4.10 can be exploited to cause a
stacked-based
buffer overflow by tricking a user into processing a specially crafted
assignments file via the e.g. asn1Coding utility.
