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.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
