Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU82973
Risk: Low
CVSSv3.1: 6.6 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-40660
CWE-ID:
CWE-285 - Improper Authorization
Exploit availability: No
DescriptionThe vulnerability allows an attacker to bypass authorization process.
The vulnerability exists due to a logic error in the authorization process. 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. An attacker with physical proximity to the system can bypass the OS logon/screen for small permanently connected tokens to computers.
MitigationUpdate the affected package opensc to the latest version.

EUVDB-ID: #VU82974
Risk: Low
CVSSv3.1: 5.8 [CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-40661
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows an attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. An attacker with physical access to the system can trigger memory corruption and execute arbitrary code with elevated privileges.
Update the affected package opensc to the latest version.
