Apple macOS High Sierra 10.13.3 – Multiple Vulnerabilities

Apple has released security updates that address multiple vulnerabilities in Apple macOS Sierra 10.12.6, 10.13.2, and OS X El Capitan 10.11.6.

This update resolves 17 vulnerabilities in the following components of the affected software: audio, curl, IOHIDFamily, kernel, LinkPresentation, QuartzCore, sandbox, security, WebKit, and Wi-Fi. The vulnerabilities are due to improper memory handling, insufficient validation of user-supplied input, improper security restrictions, and insufficient bounds checking by the affected software. An attacker could exploit some of these vulnerabilities by persuading a targeted user to open a crafted file or execute a malicious application. A successful exploit could allow the attacker to execute arbitrary code, gain elevated privileges, access sensitive information, or cause an application to terminate unexpectedly, resulting in a denial of service (DoS) condition on the targeted system.

Administrators are advised to apply the appropriate updates.
