NVD Description

Note: Versions mentioned in the description apply to the upstream libtasn1-6 package. See Remediation section below for Debian:9 relevant versions.

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.

Remediation

Upgrade Debian:9 libtasn1-6 to version 4.10-1.1 or higher.
