VLC_CVE-2021-25804_Analysis

AVI 파일은 여러 개의 트랙을 가질 수 있습니다. 예를 들어 오디오 트랙과 비디오 트랙이 있습니다. 임의 개수의 트랙을 파싱하려면 VLC는 먼저 주어진 트랙이 완료되었고 재생 가능한지 확인해야 합니다. 이를 위해 두 개의 변수가 설정됩니다. 둘 다 이름이 itrack입니다. 변수 psys는 우리의 목적에 있어 avi 파일을 나타냅니다. 따라서 완료되고 재생 가능한 트랙을 참조하는 데 사용되는 "공식" itrack 변수는 psys-itrack입니다. 이 변수는 다음 매크로로 초기화됩니다: TABINITpsys-itrack,...

CVE-2026-77396
