checksec command is inspired from
checksec.sh. It provides a
convenient way to determine which security protections are enabled in a binary.
You can use the command on the currently debugged process:
gef➤ checksec [+] checksec for '/vagrant/test-bin' Canary: No NX Support: Yes PIE Support: No No RPATH: Yes No RUNPATH: Yes Partial RelRO: Yes Full RelRO: No
Or specify directly the binary to check, for example:
$ gdb -ex "checksec ./tests/test-x86"
