Hi, The following vulnerability was published for opensc. CVE-2023-40660[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
