Several memory vulnerabilities were identified within the OpenSC packages,
particularly in the card enrollment process using pkcs15-init when a user
or administrator enrolls cards. To take advantage of these flaws, an
attacker must have physical access to the computer system and employ a
custom-crafted USB device or smart card to manipulate responses to APDUs.
This manipulation can potentially allow compromise key generation,
certificate loading, and other card management operations during
enrollment.
