Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-01-31 10:29:24 UTC
"""
VULNERABILITY

curl inadvertently kept the SSL session ID for connections in its cache even when the verify status (OCSP stapling) test failed. A subsequent transfer to the same hostname could then succeed if the session ID cache was still fresh, which then skipped the verify status check.
INFO

This issue is limited to curl built to use OpenSSL and when using TLS 1.2 only and not TLS 1.3.

The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2024-0853 to this issue.

CWE-299: Improper Check for Certificate Revocation
