Description

A flaw was found in Curl, where it 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 succeed if the session ID cache were still fresh, which then skips the verify status check.

Statement

This CVE only affects upstream Curl version 8.5.0. No Red Hat products are affected by this CVE.
