계: API Abuse
API는 호출자와 피호출자 간의 계약입니다. 가장 흔한 형태의 API 오용은 호출자가 이 계약에서 자신의 몫을 이행하지 못하기 때문에 발생합니다. 예를 들어, 프로그램이 chroot()를 호출한 후 chdir()을 호출하지 못하면 활성 루트 디렉터리를 안전하게 변경하는 방법을 지정하는 계약을 위반하는 것입니다. 라이브러리 오용의 또 다른 좋은 예는 피호출자가 호출자에게 신뢰할 만한 DNS 정보를 반환할 것으로 예상하는 것입니다. 이 경우, 호출자는 자신의 행동에 대해 특정한 가정을 함으로써(반환 값이 인증 목적으로 사용될 것으로 예상) 피호출자 API를 오용합니다. 다른 쪽에서 호출자-피호출자 계약을 위반할 수도 있습니다. 예를 들어, 코더가 하위 클래스 SecureRandom을 지정하고 임의 값이 아닌 값을 반환하는 경우 계약을 위반하는 것입니다.
Heap Inspection: Swappable Memory
Abstract
민감한 데이터가 있는 페이지를 고정시키기 위해
VirtualLock을 사용하지 마십시오. 함수가 항상 구현되는 것은 아닙니다.Explanation
Heap inspection 취약점은 암호나 암호화 키 같은 민감한 데이터가 메모리에서 삭제되지 않기 때문에 공격자에게 노출될 때 발생합니다.
VirtualLock 함수는 메모리의 페이지가 디스크에 페이지되는 것을 방지하기 위한 것입니다. 하지만, Windows 95/98/ME에서 이 함수는 스텁(stub)으로 구현되며 아무런 영향을 끼치지 않습니다. References
