descriptionThe remote host is running a version of macOS that is 10.12.x prior to 10.12.2. It is, therefore, affected by multiple vulnerabilities in the following components : - apache_mod_php - AppleGraphicsPowerManagement - Assets - Audio - Bluetooth - CoreCapture - CoreFoundation - CoreGraphics - CoreMedia External Displays - CoreMedia Playback - CoreStorage - CoreText - curl - Directory Services - Disk Images - FontParser - Foundation - Grapher - ICU - ImageIO - Intel Graphics Driver - IOFireWireFamily - IOAcceleratorFamily - IOHIDFamily - IOKit - IOSurface - Kernel - kext tools - libarchive - LibreSSL - OpenLDAP - OpenPAM - OpenSSL - Power Management - Security - syslog - WiFi - xar Note that successful exploitation of the most serious issues can result in arbitrary code execution. Furthermore, CVE-2016-6304, CVE-2016-7596, and CVE-2016-7604 also affect Mac OS X versions 10.10.5 and 10.11.6. However, this plugin does not check those versions.
