Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Cryptographic issues

EUVDB-ID: #VU86937

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-5992

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to the PKCS#1 encryption padding removal is not implemented as side-channel resistant. A remote attacker can gain access to sensitive data.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Anolis OS: 8

opensc-doc: before 0.20.0-7.0.1

opensc: before 0.20.0-7.0.1

CPE2.3 External links

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Improper Authorization

EUVDB-ID: #VU82973

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-40660

CWE-ID: CWE-285 - Improper Authorization

Exploit availability: No

Description

The 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.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Anolis OS: 8

opensc-doc: before 0.20.0-7.0.1

opensc: before 0.20.0-7.0.1

CPE2.3 External links

https://anas.openanolis.cn/errata/detail/ANSA-2024:0076


Q & A

Can this vulnerability be exploited remotely?

No. The attacker should have physical access to the system in order to successfully exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) Buffer overflow

EUVDB-ID: #VU82974

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-40661

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The 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.

Mitigation

Install updates from vendor's repository.
