Description
This module attempts to gain root privileges on Linux systems using
setuid executables compiled with AddressSanitizer (ASan).
ASan configuration related environment variables are permitted when
executing setuid executables built with libasan. The `log_path` option
can be set using the `ASAN_OPTIONS` environment variable, allowing
clobbering of arbitrary files, with the privileges of the setuid user.
This module uploads a shared object and sprays symlinks to overwrite
`/etc/ld.so.preload` in order to create a setuid root shell.
