Edit hotelnew.c to validate admin_entry input length before processing
Stack Protection Enablement
linuxCompile with stack protection flags if recompiling is possible
gcc -fstack-protector-all -D_FORTIFY_SOURCE=2 hotelnew.c
🧯 If You Can't Patch
- Restrict local access to hotel management system to trusted users only
- Implement application whitelisting to prevent unauthorized code execution
