제목 mp4v2 project has Floating Point Exception vulnerability
설명There has a FPE(Floating Point Exception) in mp4trackdump.cpp:54, function DumpTrack(). Attackers cause denial of service through carefully constructed malicious files. ``` Legend: code, data, rodata, value Stopped reason: SIGFPE 0x0000000000427aa6 in DumpTrack (mp4file=0xf80d10, tid=0x1) at /root/mp4v2/build/mp4v2/util/mp4trackdump.cpp:54 54 msectime /= timescale; gdb-peda$ p timescale $1 = 0x0 gdb-peda$ ``` I use gdb debug this program, you can see 'timescale' is 0 when open the malicious files. It cause the SIGFPE.
