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.

CVE-2017-6891 Libtasn1 vulnerability
Title: Libtasn1 vulnerability
Summary: Libtasn1 could be made to crash or run programs as your login if it
opened a specially crafted file.
Jakub Jirasek discovered that GnuTLS incorrectly handled certain
assignments files. If a user were tricked into processing a specially
crafted assignments file, a remote attacker could possibly execute arbirary
code.
Instructions: In general, a standard system update will make all the necessary changes.
