 - WebKit (CVE-2016-4666, CVE-2016-4677, CVE-2016-7578)

The version of iOS running on the mobile device is prior to 10.1. It is, therefore, affected by multiple vulnerabilities :

  - A flaw exists in the FaceTime component when handling     relayed calls due to inconsistencies in the user     interface. A man-in-the-middle attacker can exploit this     issue to cause a relayed call to continue to transmit     audio while the call appears to be terminated.
    (CVE-2016-4635)

  - An out-of-bounds read error exists in the FontParser     component when handling specially crafted font files     that allows an unauthenticated, remote attacker to     disclose sensitive information. (CVE-2016-4660)

  - An unspecified flaw exists in the Sandbox Profiles     component that allows a local attacker, via a specially     crafted application, to disclose the metadata of photo     directories. (CVE-2016-4664)

  - An unspecified flaw exists in the Sandbox Profiles     component that allows a local attacker, via a specially     crafted application, to disclose the metadata of audio     recordings. (CVE-2016-4665)

  - Multiple memory corruption issues exist in Webkit due     to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit these to     execute arbitrary code. (CVE-2016-4666, CVE-2016-4677)

  - Multiple unspecified flaws exist in the System Boot     component, within MIG generated code, due to improper     validation of input. A local attacker can exploit these     to terminate the system or execute arbitrary code with     elevated privileges. (CVE-2016-4669)

  - A flaw exists in the Security component due to the     program logging the length of passwords. A local     attacker can exploit this to disclose sensitive     information. (CVE-2016-4670)

  - A memory corruption issue exists in the CoreGraphics     component when handling specially crafted JPEG files. An     unauthenticated, remote attacker can exploit this, via a     specially crafted file, to cause a denial of service     condition or the execution of arbitrary code.
    (CVE-2016-4673)

  - An unspecified logic issue exists in libxpc that allows     a local attacker to execute arbitrary code with root     privileges. (CVE-2016-4675)

  - A flaw exists in libarchive due to improper path     validation when creating temporary files during archive     extraction. An unauthenticated, remote attacker can     exploit this, via a symlink attack, to overwrite     arbitrary files. (CVE-2016-4679)

  - An unspecified flaw exists in the Kernel component due     to improper sanitization of input. A local attacker can     exploit this to disclose kernel memory contents.
    (CVE-2016-4680)

  - A flaw exists in the Contacts component due to a failure     to revoke an application's access to the Address Book     after its access has been removed in Settings. A local     attacker can exploit this to cause access to persist     after it should have been removed. (CVE-2016-4686)

  - A flaw exists in the CFNetworks component when handling     proxy credentials that allows a man-in-the-middle     attacker to disclose sensitive user information.
    (CVE-2016-7579)

The remote host is running a version of Mac OS X that is 10.12.x prior to macOS 10.12.1. It is, therefore, affected by multiple vulnerabilities in the following components :

  - ATS
  - AppleMobileFileIntegrity
  - AppleSMC
  - CFNetwork Proxies
  - CoreGraphics
  - FaceTime
  - FontParser
  - IDS - Connectivity
  - Kernel
  - libarchive
  - libxpc
  - ntfs
  - Security
  - Thunderbolt

Note that successful exploitation of the most serious issues can result in arbitrary code execution.
