An issue was discovered in certain Apple products. iOS before 10.3.3 is affected. macOS before 10.12.6 is affected. tvOS before 10.2.2 is affected. watchOS before 3.2.3 is affected. The issue involves the "Contacts" component. A buffer overflow allows remote attackers to execute arbitrary code or cause a denial of service (application crash).
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.
