Opensc: potential pin bypass when card tracks its own login state
Résumé
Opensc: potential pin bypass when card tracks its own login state
Description d'origine
La description telle que publiée par la source (souvent en anglais).
A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.
