이 보안 업데이트는 "적용 대상" 섹션에 나열된 지원되는 Windows 버전의 보안 부팅 DBX를 개선합니다. 주요 변경 사항은 다음과 같습니다. UEFI (통합 확장 펌웨어 인터페이스) 기반 펌웨어가 있는 Windows 디바이스는 보안 부팅을 사용 설정하여 실행할 수 있습니다. DBX (보안 부팅 금지 서명 데이터베이스)는 UEFI 모듈이 로드되지 않도록 합니다. 이 업데이트는 DBX에 모듈을 추가합니다. 보안 기능 바이패스 취약성은 보안 부팅에 있습니다. 취약점을 성공적으로 악용한 공격자는 보안 부팅을 우회하고 신뢰할 수 없는 소프트웨어를 로드할 수 있습니다.
