Found a null pointer deference in mfmp4srcsnk.dll in latest windows 10 by accident. Download mov file here: https://github.com/MozillaSecurity/fuzzdata/blob/master/samples/samples.mplayerhq.hu/ffmpeg-bugs/roundup/issue2490/invalid_mov_time.mov Your explorer will crash. If not use windows media player. (2788.3588): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling. This exception may be expected and handled. eax=00000000 ebx=180bced8 ecx=5aaa2e20 edx=44445111 esi=5aaa2e20 edi=00000000 eip=5aa7d16e esp=1793f374 ebp=1793f3b4 iopl=0 nv up ei pl zr na pe cy cs=0023 ss=002b ds=002b es=002b fs=0053 gs=002b efl=00010247 mfmp4srcsnk!CQTMovie::FinalParseAtom+0x16e: 5aa7d16e 8b08 mov ecx,dword ptr [eax] ds:002b:00000000=???????? I know MSRC usually do not fix null pointer deference but I reported to them just in case. And as I expected they closed the case. _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
