Descriptions

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.

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. Insufficient or missing checking of return values of functions leads to unexpected work with variables that have not been initialized.

This update for opensc fixes the following issues. Incorrect handling of the length of buffers or files in pkcs15init. Incorrect handling length of buffers or files in libopensc. Uninitialized values after incorrect or missing checking return values of functions in pkcs15init. Uninitialized values after incorrect or missing checking return values of functions in libopensc. Uninitialized values after incorrect check or usage of APDU response values in libopensc. Usage of uninitialized values in libopensc and pkcs15init. Heap buffer overflow in OpenPGP driver when generating key.
