Multiple vulnerabilities have been discovered in Apple Products, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Threat IntelligenceApple is aware of a report that CVE-2023-32367 may have been actively exploited.

Technical Summary Multiple vulnerabilities have been discovered in Apple Products, the most severe of which could allow for arbitrary code execution.
Recommendations
Apply the stable channel update provided by Apple to vulnerable systems immediately after appropriate testing. Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. Restrict use of certain websites, block downloads/attachments, block JavaScript, restrict browser extensions, etc. Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring. Train users to be aware of access or manipulation attempts by an adversary to reduce the risk of successful spearphishing, social engineering, and other techniques that involve user interaction.
