The issue was addressed with improved memory handling. This issue is fixed in macOS Ventura 13. Processing a maliciously crafted gcx file may lead to unexpected app termination or arbitrary code execution.
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.
