How to fix?

Upgrade Alpine:3.9 libtasn1 to version 4.12-r1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libtasn1 package and not the libtasn1 package as distributed by Alpine. See How to fix? for Alpine:3.9 relevant fixed versions and status.

The _asn1_check_identifier function in GNU Libtasn1 through 4.12 causes a NULL pointer dereference and crash when reading crafted input that triggers assignment of a NULL value within an asn1_node structure. It may lead to a remote denial of service attack.
