Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 11.0
Description:   Several vulnerabilities were reported in Apple Safari. A remote user can execute arbitrary code on the target system. A remote user can spoof the address bar. A remote user can conduct cross-site scripting attacks.

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].

A remote user can trigger a memory corruption error in the WebKit component to execute arbitrary code [CVE-2017-7081, CVE-2017-7087, CVE-2017-7091, CVE-2017-7092, CVE-2017-7093, CVE-2017-7094, CVE-2017-7095, CVE-2017-7096, CVE-2017-7098, CVE-2017-7099, CVE-2017-7100, CVE-2017-7102, CVE-2017-7104, CVE-2017-7107, CVE-2017-7111, CVE-2017-7117, CVE-2017-7120].

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.

A remote user can trigger a cross-origin permissions error in the WebKit component to obtain cookies for other domains [CVE-2017-7090].

A remote user can trigger an input validation flaw in the WebKit component to conduct cross site scripting attacks [CVE-2017-7109].

A remote user can exploit a cookie permissions flaw to track users in Safari private browsing mode [CVE-2017-7144].

A user may be able to obtain Safari Private window website data [CVE-2017-7142].

Impact:   A remote user can execute arbitrary code on the target system.

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).
