CVE-2024-8096 is fixed in 6 products on 1 platform, first by curl 7.68.0-1ubuntu2.24, released September 10, 2024. It is not reported as exploited. Patch Radar priority: Routine.
When curl is told to use the Certificate Status Request TLS extension,often referred to as OCSP stapling, to verify that the server certificateis valid, it might fail to detect some OCSP problems and instead wronglyconsider the response as fine. If the returned status reports anothererror than 'revoked' (like for example 'unauthorized') it is not treated asa bad certficate.
