macOS 10.14.x < 10.14.6 SU2 / 10.13.x < 10.13.6 Update 2019-005 / 10.12.x < 10.12.6 Update 2019-005 Out-of-Bounds Read Vulnerability

High Nessus Plugin ID 129467

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 7.4


The remote host is missing a macOS update that fixes an out-of-bounds read vulnerability.


The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Supplemental Update 2, 10.13.x prior to 10.13.6 Security Update 2019-005, or 10.12.x prior to 10.12.6 Security Update 2019-005. It is, therefore, affected by an out-of-bounds read vulnerability. An attacker could exploit this vulnerability to cause an application crash, or potentially achieve arbitrary code execution.

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


Upgrade to macOS 10.14.x < 10.14.6 SU2 / 10.13.x < 10.13.6 Update 2019-005 / 10.12.x < 10.12.6 Update 2019-005 or later.
