Vulnerability
CVE-2018-4237 is a logic error in the libxpc component of Apple operating systems, affecting iOS before 11.4, macOS before 10.13.5, tvOS before 11.4, and watchOS before 4.3.1 [1][2][3][4]. This error allows a crafted application to exploit the vulnerability.
Exploitation
An attacker requires the ability to run a malicious application on the target device. No special privileges or user interaction beyond launching the app are needed. The crafted app triggers the logic error in libxpc to gain elevated privileges [1].
