Detailed vulnerability description
The vulnerability allows an attacker to bypass implemented security restrictions.
The vulnerability exists due to a boundary error in the pkcs15-init tool in OpenSC. An attacker with physical access to the system can use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs.
