CVE-2024-0853  (opens in a new tab)
CWE-295  (opens in a new tab)

How to fix?

Upgrade Alpine:3.21 curl to version 8.6.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Alpine. See How to fix? for Alpine:3.21 relevant fixed versions and status.

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.
