Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 11.0
Description:   Multiple vulnerabilities were reported in Apple iOS. A remote user on the wireless network can obtain potentially sensitive information and execute arbitrary code. A remote user can cause denial of service conditions on the target system. A remote user can spoof the address bar. A remote user can conduct cross-site scripting attacks.

A remote user on the wireless network can trigger a memory corruption error in the Wi-Fi component to execute arbitrary code with kernel privileges [CVE-2017-7103, CVE-2017-7105, CVE-2017-7108, CVE-2017-7110, CVE-2017-7112].

A remote user on the wireless network can trigger a race condition in the Wi-Fi component to execute arbitrary code with kernel privileges [CVE-2017-7115].

A remote user on the wireless network can can trigger a input validation flaw in the Wi-Fi component to read restricted kernel memory [CVE-2017-7116].

A remote user in a privileged network position can exploit a validation flaw in Exchange ActiveSync in AutoDiscover V1 when setting up an Exchange account to erase the target device [CVE-2017-7088].

A remote user can use a specially crafted iBooks file trigger a memory handling error in the iBooks component to cause denial of service conditions [CVE-2017-7072].

A remote user can use a specially crafted image to trigger a validation flaw in the Messages component to cause denial of service conditions [CVE-2017-7118].

A permissions error in MobileBackup Backup may cause a backup to be unencrypted when set to perform only encrypted backups [CVE-2017-7133].

A remote user can create specially crafted HTML that, when loaded by the target user, will spoof the address bar [CVE-2017-7085, CVE-2017-7106].

The WebKit component does not properly filter HTML code from user-supplied input before displaying the input [CVE-2017-7089]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will run in the security context of an arbitrary site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Anton Lopanitsyn of ONSEC, Frans Rosen of Detectify, Don Sparks of HackediOS.com, Gal Beniamini of Google Project Zero, Ilya Nesterov, Maxim Goncharov, Jedrzej Krysztofiak, Kiki Jiang, Jason Tokoph, Oliver Paukstadt of Thinking Objects GmbH (to.com), Xinshu Dong and Jun Hao Tan of Anquan Capital, and xisigr of Tencent's Xuanwu Lab (tencent.com) reported these vulnerabilities.

Impact:   A remote user on the wireless network can execute arbitrary code with kernel-level privileges.

A remote user on the wireless network can obtain portions of kernel memory.

A remote user can cause denial of service conditions.

A remote user can spoof the address bar.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with an arbitrary site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   The vendor has issued a fix (11.0).

The vendor advisory is available at:

https://support.apple.com/en-us/HT208112

Vendor URL:  support.apple.com/en-us/HT208112 (Links to External Site)
Cause:   Access control error, Input validation error, State error
