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 Ubuntu.
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.
