Dear Maintainer,
this crash happens when only one command line argument is given.
(e.g. "M2VRequantiser --help" or as from the bug opener "M2VRequantiser --NN)
--- m2vrequantiser-1.1.orig/main.c
+++ m2vrequantiser-1.1/main.c
@@ -2315,7 +2315,7 @@ int main (int argc, const char * argv[])
if (argc < 5) { USAGE }
delta_bright = atoi(argv[4]);
#else
- if (argc < 2) { USAGE }
+ if (argc < 3) { USAGE }
#endif
fact_x = atof(argv[1]);
sscanf(argv[2], "%lld", &orim2vsize);
The sscanf above accesses argv on index 2 (third element) - this way it it
crashing.
This is intended to be prevented in the changed line where I think the
comparison
with argc is off by one.
Kind regards,
Bernhard
