+Subject: [PATCH] Avoid buffer overflow in RC4 loop comparison (#336)
+
+The rc4 function iterates over a buffer of size buffer_len who's maximum
+value is INT_MAX with a counter of type short that is not guaranteed to
+have maximum size INT_MAX.
+
+In circumstances where short is narrower than int and where buffer_len
+is larger than the maximum value of a short, it may be possible to loop
+infinitely as counter will overflow and never be greater than or equal
+to buffer_len.
+
+The solution is to make the comparison be between types of equal width.
+This commit defines counter as an int.
