Apple macOS Multiple Security Vulnerabilities



Date Discovered

May 13, 2019


Apple macOS is prone to multiple security vulnerabilities. An attacker can leverage these issues to bypass security restrictions and perform unauthorized actions, obtain sensitive information, execute arbitrary code within the context of the application or gain elevated privileges. Failed exploits will result in denial-of-service conditions.

Technologies Affected

  • Apple macOS 10.12.1
  • Apple macOS 10.12.2
  • Apple macOS 10.12.3
  • Apple macOS 10.12.4
  • Apple macOS 10.12.5
  • Apple macOS 10.13.1
  • Apple macOS 10.13.2
  • Apple macOS 10.13.3
  • Apple macOS 10.13.4
  • Apple macOS 10.13.5
  • Apple macOS 10.14.1
  • Apple macOS 10.14.2
  • Apple macOS 10.14.3


Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Allow only trusted and accountable users to have local access to computers.

Run all software as a nonprivileged user with minimal access rights.
Ensure that all nonadministrative tasks, such as browsing the web and reading email, are performed as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from a successful exploit.

Do not accept or execute files from untrusted or unknown sources.
To limit exposure to these and other latent vulnerabilities, never handle files that originate from unfamiliar or untrusted sources.

Do not follow links provided by unknown or untrusted sources.
To reduce the likelihood of successful exploits, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.

Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit memory corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
