An issue was discovered in certain Apple products. macOS before 10.12.2 is affected. The issue involves the "Grapher" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted .gcx file.
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.
