The Safari Extensions implementation in Apple Safari before 9 does not require user confirmation before replacing an installed extension, which has unspecified impact and attack vectors.

The version of Safari installed on the remote host is prior to 9.0. It is, therefore, affected by multiple vulnerabilities in the following components :

 - Safari
 - Safari Downloads
 - Safari Extensions
 - Safari Safe Browsing
 - WebKit
 - WebKit CSS
 - WebKit JavaScript Bindings
 - WebKit Page Loading
 - WebKit Plug-ins

The remote host is running a version of Mac OS X that is 10.6.8 or later but prior to 10.11. It is, therefore, affected by multiple vulnerabilities in the following components :

  - AppleEvents
  - Audio
  - bash
  - Certificate Trust Policy
  - CFNetwork Cookies
