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_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.

Remediation

Upgrade Debian:9 libtasn1-6 to version 3.6-1 or higher.
