NVD Description

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

The _asn1_extract_der_octet function in lib/decoding.c in GNU Libtasn1 before 4.5 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a crafted certificate.

Remediation

Upgrade Debian:9 libtasn1-6 to version 4.4-3 or higher.
