How to fix?

Upgrade Debian:10 libtasn1-6 to version 3.6-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libtasn1-6 package and not the libtasn1-6 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

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.
