The Use After Free vulnerability was identified within the AuthentIC driver in OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls or modifies cards. An attacker must have physical access to the computer system to take advantage of this flaw. The attack requires a crafted USB device or smart card to present the system with specially crafted responses to the APDUs, which are considered high complexity and low severity. This manipulation can potentially allow for compromising card management operations during enrollment.
