Recent Openscproject Opensc Security Vulnerabilities
A flaw was found in OpenSC packages that allow a potential PIN bypass
CVE-2023-40660
6.6 - Medium
- November 06, 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 compromise the system without the user's awareness.
authentification
Several memory vulnerabilities were identified within the OpenSC packages
CVE-2023-40661
6.4 - Medium
- November 06, 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.
Buffer Overflow
An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling symmetric key encryption
CVE-2023-4535
3.8 - Low
- November 06, 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.
Out-of-bounds Read
Stack overflow vulnerability in OpenSC smart card middleware before 0.23
CVE-2021-34193
7.5 - High
- August 22, 2023
Stack overflow vulnerability in OpenSC smart card middleware before 0.23 via crafted responses to APDUs.
Memory Corruption
A vulnerbility was found in OpenSC
CVE-2023-2977
7.1 - High
- June 01, 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. In cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is possible.
