Fix commit - 88fa1ebfa21b5deaaad2dc88ecd9f6af91796cf7 This commit added return value check for sscanf() that parses the input buffer for four input items. However, the return value check is incorrect, as it checks for one input item instead of four which is what it is expecting in the input buffer. As a result, sscanf() will always fail even when the input buffer is correct.
