Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Improper check for certificate revocation

EUVDB-ID: #VU85927

Risk: Low

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

CVE-ID: CVE-2024-0853

CWE-ID: CWE-299 - Improper Check for Certificate Revocation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass OCSP verification.

The vulnerability exists due to curl inadvertently keeps the SSL session ID for connections in its cache even when the verify status (OCSP stapling) test has failed. A subsequent transfer to the same hostname will be successful if the session ID cache is still fresh, which leads to skipping the verify status check. As a result, OCSP verification is always successful for all subsequent TLS sessions.

Mitigation

Install update from vendor's website.

Vulnerable software versions
