Description Arvid Requate

Upstream Debian package version 4.2-3+deb8u3 fixes:

* 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)
