Description-en: Bash script to test executable properties
Modern Linux distributions offer some mitigation techniques to make it harder
to exploit software vulnerabilities reliably. Mitigations such as RELRO,
NoExecute (NX), Stack Canaries, Address Space Layout Randomization (ASLR) and
Position Independent Executables (PIE) have made reliably exploiting any
vulnerabilities that do exist far more challenging. The checksec.sh script is
designed to test what standard Linux OS and PaX security features are being
used.
