**Name of the Vulnerable Software and Affected Versions** Apple iOS versions prior to 9.3 Apple OS X versions prior to 10.11.4 Apple watchOS versions prior to 2.2 **Description** The issue is related to the incorrect operation of a cryptographic protection mechanism in the operating systems. This could allow a remote attacker to influence the confidentiality of protected information.

For Apple OS X versions prior to 10.11.4, update to version 10.11.4 or later to resolve the issue. For Apple watchOS versions prior to 2.2, update to version 2.2 or later to resolve the issue.
