Description Ian Zimmerman 2018-02-08 16:31:22 UTC

According to the RedHat bugzilla [1]:

The _asn1_check_identifier function in GNU Libtasn1 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 denial of service attack.
