How to fix?

Upgrade SLES:15.0 gnutls to version 3.6.2-6.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gnutls package and not the gnutls package as distributed by SLES. See How to fix? for SLES:15.0 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.
