An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. macOS before 10.12.5 is affected. tvOS before 10.2.1 is affected. watchOS before 3.2.2 is affected. The issue involves the "Foundation" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via crafted data.

Versions of Apple TV earlier than 10.2.1 are affected by multiple vulnerabilities :

 - A flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderLayer objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A logic flaw exists that allows a universal cross-site scripting (UXSS) attack. The issue is triggered when handling WebKit Editor commands. This may allow a context-dependent attacker to create a specially crafted web page that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and any website. 

This product is also affected by vulnerabilities found in the following components:

 - AVEVideoEncoder
 - CoreAudio
 - CoreFoundation
 - Foundation
 - IOSurface
 - Kernel
 - SQLite
 - TextInput
 - WebKit
 - Web Inspector

The remote host is running a version of Mac OS X version 10.x prior to 10.12.5, and is affected by multiple vulnerabilities :

 - An overflow condition exists in the '_XGetWindowMovementGroup()' function within the WindowServer component that is triggered as certain input is not properly validated. This may allow a local attacker to cause a stack-based buffer overflow and potentially execute arbitrary code with the privileges of WindowServer.
 - An unspecified flaw exists in the Intel graphics driver. This may allow a local attacker to corrupt memory and potentially execute arbitrary code with kernel-level privileges.
 - An unspecified flaw exists in the NVIDIA graphics drivers. This may allow a local attacker to corrupt memory and potentially execute arbitrary code with kernel-level privileges.
 - A flaw exists in the speechsynthesisd service, as unsigned dynamic libraries (.dylib) are improperly validated before being loaded. This may allow a local attacker to bypass an application's sandbox and execute arbitrary code with elevated privileges.
 - An unspecified flaw exists in the Speech Framework. This may allow an attacker to escape an application sandbox.
 - A certificate validation flaw exists in 802.1X authentication that is triggered in EAP-TLS when a certificate has changed. This may allow a context-dependent attacker to disclose user network credentials.
 - A type confusion flaw exists in SQLite that is triggered as certain input related to 'snippet' is not properly validated. With specially crafted web content, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.

The version of iOS running on the mobile device is prior to 10.3.2, and is affected by multiple vulnerabilities :

 - A use-after-free error exists in the handling of RenderElement objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderLayer objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderInline objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An unspecified flaw exists related to the certificate trust policy that is triggered when handling trust acceptance. This may allow a context-dependent attacker to potentially cause untrusted certificates to be treated as trusted.
 - An unspecified flaw exists in the Safari history menu. With a specially crafted web page, a context-dependent attacker can cause an application denial of service.
 - A logic flaw exists that allows a universal cross-site scripting (UXSS) attack. The issue is triggered when handling WebKit Editor commands. This may allow a context-dependent attacker to create a specially crafted web page that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and any website.
 - A type confusion flaw exists in SQLite that is triggered as certain input related to 'snippet' is not properly validated. With specially crafted web content, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.
