CID 12526 - SECURE_CODING
[VERY RISKY]. Using "sscanf" can cause a buffer overflow when done incorrectly. sscanf() assumes an arbitrarily large string, so callers must use correct precision specifiers or never use sscanf(). Use correct precision specifiers or do your own parsing.
293 if (sscanf (str.substr (start + 6).c_str (), "%d", &buttonNum) == 1)
294 {
295 mButton = buttonNum;
296 mModifiers = mods;

298 return true;
