Apple TV < 10.0.1 Multiple Vulnerabilities
According to its banner, the version of Apple TV on the remote device is prior to 10.0.1. It is, therefore, affected by multiple vulnerabilities : - A flaw exists in WebKit when handling the location attribute that allows an unauthenticated, remote attacker to bypass the cross-origin policies and...
task_t considered harmful
Posted by Ian Beer, Project Zero This post discusses a design issue at the core of the XNU kernel which powers iOS and MacOS. Apple have shipped two iterations of mitigations followed yesterday by a large refactor in MacOS 10.12.1/iOS 10.1. We’ll look at the bugs, how they can be exploited to...
