OpenSC pam_p11 0.2.0 and 0.3.0 - Buffer Overflow via Long Smart Card Signature
An issue was discovered in the pam_p11 component 0.2.0 and 0.3.0 for OpenSC. If a smart card creates a signature with a length longer than 256 bytes, this triggers a buffer overflow. This may be the case for RSA keys with 4096 bits depending on the signature scheme.

OpenSC - Out-of-bounds Read in MyEID Driver Symmetric Key Encryption
An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling symmetric key encryption. Exploiting this flaw requires an attacker to have physical access to the computer and a specially crafted USB device or smart card. This flaw allows the attacker to manipulate APDU responses and potentially gain unauthorized access to sensitive data, compromising the system's security.
