Synopsis

The remote host is missing a macOS or Mac OS X security update or supplemental update that fixes multiple vulnerabilities

Description

The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6 Security Update 2020-006 High Sierra, or 10.14.x prior to 10.14.6 Security Update 2020-006 Mojave. It is, therefore, affected by multiple vulnerabilities :

 - Processing a maliciously crafted font may lead to arbitrary code execution. (CVE-2020-27930)

 - A malicious application may be able to execute arbitrary code with kernel privileges. (CVE-2020-27932)

 - A malicious application may be able to disclose kernel memory. (CVE-2020-27950)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

Solution

Upgrade to macOS 10.13.6 Security Update 2020-006 / 10.14.6 Security Update 2020-006 or later.
