An issue was discovered in certain Apple products. iOS before 11.3.1 is affected. macOS before 10.13.4 Security Update 2018-001 is affected. tvOS before 11.4 is affected. watchOS before 4.3.1 is affected. The issue involves the "Crash Reporter" component. It allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted app that replaces a privileged port name.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
