Upstream source description

A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker could use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.
