An issue was discovered in certain Apple products. macOS before 10.12.1 is affected. The issue involves the "AppleSMC" component. It allows local users to gain privileges or cause a denial of service (NULL pointer dereference) via unspecified vectors.

The remote host is running a version of Mac OS X version 10.x prior to 10.12.1, and is affected by multiple vulnerabilities in the following components :

 - AppleMobileFileIntegrity (CVE-2016-7584)
 - AppleGraphicsControl (CVE-2016-4662)
 - AppleSMC (CVE-2016-4678)
 - ATS (CVE-2016-4667, CVE-2016-4674)
 - CFNetwork Proxies (CVE-2016-7579)
 - CoreGraphics (CVE-2016-4673)
 - Core Image (CVE-2016-4681)
 - FaceTime (CVE-2016-7577)
 - FontParser (CVE-2016-4660, CVE-2016-4688)
 - IDS - Connectivity (CVE-2016-4721)
 - ImageIO (CVE-2016-4671, CVE-2016-4682, CVE-2016-4683)
 - Kernel (CVE-2016-4669, CVE-2016-7613)
 - libarchive (CVE-2016-4679)
 - libxpc (CVE-2016-4675)
 - ntfs (CVE-2016-4661)
 - NVIDIA Graphics Drivers (CVE-2016-4663)
 - Security (CVE-2016-4670)
 - Thunderbolt (CVE-2016-4780)

Versions of Apple TV earlier than 10.0.1 are vulnerable to the following issues :

 - A flaw exists in WebKit when handling the location attribute that allows a unauthenticated, remote attacker to bypass the cross-origin policies and disclose sensitive user information. (CVE-2016-4613)
 - 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 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 NULL pointer dereference flaw exists in AppleSMC's smcHandleYPCEvent facility that is due to insufficient locking, which may allow a local attacker to gain elevated privileges. (CVE-2016-4678)
 - 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 CFNetwork Proxies component when handling proxy credentials that allows a man-in-the-middle attacker to disclose sensitive user information. (CVE-2016-7579)
 - A race condition exists in multiple IOKit drivers related to how they use task struct pointers.  This may allow a local attacker to potentially execute arbitrary code with kernel-level privileges. (CVE-2016-7613)

Note that only 4th generation models are affected by these vulnerabilities.

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.
