FIXES APPLIED:
1. Printf format string vulnerability in show_spinner()
- Lines 733, 736: Use proper %s formatting for message variable
- Prevents format string attacks if function is called with % in message
- Currently dead code (never called), but good practice for future reuse
2. Maldet PID validation - strengthen edge case handling
- Line 1273: Add explicit [ "$pid" -gt 0 ] check before kill -0
- Prevents theoretical edge case where $! could be 0
- Makes PID validation more robust against edge cases
These are hardening fixes for LOW-risk issues found in comprehensive audit.
AUDIT SUMMARY (Passes 7-9):
- 4 low-risk issues identified through deep scrutiny
- 2 issues fixed (printf format string, PID validation)
- 2 issues noted but deferred (negative elapsed time, timeout documentation)
- Script remains in excellent condition for production testing
All critical and blocking issues resolved ✅
Script ready for comprehensive functional testing ✅
