개요 CVE-2016-7190 0은 ChakraCore의 Array.map 함수에서 발생하는 힙 오버플로우로, 인접한 메모리를 덮어쓸 수 있습니다. 임의 읽기-쓰기 액세스를 얻는 주요 아이디어는 먼저 여러 개의 연속된 JavaScript 정수 배열을 할당한 다음, 오버플로우를 악용하여 하나의 배열 크기를 조작하는 것입니다. 그런 다음 이 배열을 활용해 Uint8Array의 기본 주소를 읽거나 쓰고자 하는 임의의 주소로 변경합니다. 이 추가 단계가 필요한 이유는 오버플로우가 오버플로우된 정수 배열 크기의 2배로 제한되기 때문입니...
