opensc-0.20.0-7.el8_9

The OpenSC set of libraries and utilities provides support for working with smart cards. OpenSC focuses on cards that support cryptographic operations and enables their use for authentication, mail encryption, or digital signatures.

Security Fix(es):

* OpenSC: Potential PIN bypass when card tracks its own login state (CVE-2023-40660)
* OpenSC: multiple memory issues with pkcs15-init (enrollment tool) (CVE-2023-40661)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2023-40660
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.
CVE-2023-40661
Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise key generation, certificate loading, and other card management operations during enrollment.
