S\u00e4kerhetsforskare fr\u00e5n Google har uppt\u00e4ckt en s\u00e5rbarhet (CVE-2022-2566) i biblioteket libavformat, som ing\u00e5r i multimediapaketet FFmpeg. S\u00e5rbarheten g\u00f6r det m\u00f6jligt f\u00f6r en angripare att exekvera kod n\u00e4r ett modifierat mp4-formatfil behandlas p\u00e5 offerets system. S\u00e5rbarheten kvarst\u00e5r fr\u00e5n FFmpeg-version 5.1 och \u00e5tg\u00e4rdades i version 5.1.2 av FFmpeg. <\/p>\n

S\u00e5rbarheten orsakas av ett fel i ber\u00e4kningen av buffertstorleken i funktionen build_open_gop_key_points(), vilket leder till ett heltal\u00f6verfl\u00f6d vid behandling av vissa parametrar och allokering av en block med minne som \u00e4r mindre \u00e4n vad som kr\u00e4vs. F\u00f6r att demonstrera m\u00f6jliga angrepp har en prototyp av ett exploit publicerats.
