https://notcve.org/view.php?id=CVE-2023-5992
31 Jan 2024 — A vulnerability was found in OpenSC where PKCS#1 encryption padding removal is not implemented as side-channel resistant. This issue may result in the potential leak of private data. Se encontró una vulnerabilidad en OpenSC donde la eliminación del relleno de cifrado PKCS#1 no se implementa como resistente al canal lateral. Este problema puede resultar en una posible filtración de datos privados. It was discovered that OpenSC did not correctly handle certain memory operations, which could lead to a use-afte... • https://access.redhat.com/errata/RHSA-2024:0966 • CWE-203: Observable Discrepancy •
CVSS: 6.8EPSS: 0%CPEs: 3EXPL: 0CVE-2023-40661 – Opensc: multiple memory issues with pkcs15-init (enrollment tool)
https://notcve.org/view.php?id=CVE-2023-40661
06 Nov 2023 — 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.

https://notcve.org/view.php?id=CVE-2023-40660
06 Nov 2023 — 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 compromis... • http://www.openwall.com/lists/oss-security/2023/12/13/2 • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2023-4535
06 Nov 2023 — 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.

https://notcve.org/view.php?id=CVE-2023-2977
01 Jun 2023 — A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context. The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. • https://access.redhat.com/security/cve/CVE-2023-2977 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
