Created attachment 8693833 [details] call_stack.txt Found fuzzing ffmpeg commit: 6b978dadc654906130de46a8b83b6f67f90d3e17 This is an Undefined behavior sanitizer (UBSan) run time error. libavformat/utils.c:922:35: runtime error: signed integer overflow: -2450238577049583619 - 9223090561878065151 cannot be represented in type 'long long' I am marking it as security as precaution. Feel free to open it if this is not necessary.
not security relevant, and very likely no bug at the binary level just undefined in the C source. Will push a fix to ffmpeg
Should be fixed in upstream commit cafb19560401612a07760d230a50d9c1d0564daf. Can you verify please, Tyson?
