An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. Safari before 10.1.1 is affected. tvOS before 10.2.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to conduct Universal XSS (UXSS) attacks via a crafted web site that improperly interacts with WebKit Editor commands.

The remote host is affected by the vulnerability described in GLSA-201706-15 (WebKitGTK+: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in WebKitGTK+. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attack can use multiple vectors to execute arbitrary code or       cause a denial of service condition.
  Workaround :

    There is no known workaround at this time.

The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 10.1.1. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the history menu     functionality. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.
    (CVE-2017-2495)

  - Multiple memory corruption issues exist in the WebKit     component due to improper validation of user-supplied     input. An unauthenticated, remote attacker can exploit     these issues, by convincing a user to visit a specially     crafted website, to execute arbitrary code.
    (CVE-2017-2496, CVE-2017-2505, CVE-2017-2506,     CVE-2017-2514, CVE-2017-2515, CVE-2017-2521,     CVE-2017-2525, CVE-2017-2526, CVE-2017-2530,     CVE-2017-2531, CVE-2017-2538, CVE-2017-2539,     CVE-2017-2544, CVE-2017-2547, CVE-2017-6980,     CVE-2017-6984)

  - A memory corruption issue exists in the WebKit Web     Inspector component that allows an unauthenticated,     remote attacker to execute arbitrary code.
    (CVE-2017-2499)

  - An address bar spoofing vulnerability exists due to     improper state management. An unauthenticated, remote     attacker can exploit this to spoof the address in the     address bar. (CVE-2017-2500, CVE-2017-2511)

  - Multiple universal cross-site scripting (XSS)     vulnerabilities exist in WebKit due to improper handling     of WebKit Editor commands, container nodes, pageshow     events, frame loading, and cached frames. An     unauthenticated, remote attacker can exploit this, via a     specially crafted web page, to execute arbitrary script     code in a user's browser session. (CVE-2017-2504,     CVE-2017-2508, CVE-2017-2510, CVE-2017-2528,     CVE-2017-2549)

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

Versions of Safari prior to 10.1.1 are affected by multiple vulnerabilities :

 - 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.
 - 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 flaw exists related to an inconsistent user interface. This may allow a context-dependent attacker to spoof the address bar.
 - A logic flaw exists that allows a UXSS attack. The issue is triggered when handling container nodes. 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 flaw exists related to an inconsistent user interface. This may allow a context-dependent attacker to spoof the address bar.
