Name of the Vulnerable Software and Affected Versions Apple iOS versions prior to 9.1

Description The issue is related to the OCSP client in the iOS operating system, which does not properly check the expiration date of a certificate. This can be exploited by a remote attacker to spoof a valid certificate by using access to a revoked certificate.

Recommendations For Apple iOS versions prior to 9.1, update to version 9.1 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive operations that rely on certificate validation until the update is applied.
