The project issue is: https://github.com/xiaozhuai/imageinfo/issues/1#issue-1600041028
Vulnerability function:
```cpp
off_t offset = 0; // typedef long _off_t; off_t offset = 0;
off_t end = metaLength;
while (offset < end) {
uint32_t boxSize = buffer.readU32BE(offset); // uint32_t readU32BE;
if (buffer.cmpAnyOf(offset + 4, 4, {"iprp", "ipco"})) {
end = offset + boxSize;
offset += 8;
} else if (buffer.cmp(offset + 4, 4, "ispe")) {
width = buffer.readU32BE(offset + 12);
height = buffer.readU32BE(offset + 16);
return true;
} else {
offset += boxSize;
}
}
