Deliverance 0.018-daf9452 File Descriptor Fuzzer

Deliverance 0.018-daf9452 File Descriptor Fuzzer
Posted May 24, 2022
Authored by Marshall Whittaker | Site github.com

Deliverance is a file descriptor fuzzer written in bash. It injects random data into file descriptors of pids associated with a process until the program crashes, then outputs the results of what caused the crash. It leaves behind files that were used as input for the last 2 minutes before the fault, useful for reproduction.

# Useage: ./deliverance.sh firefox
# Note: Some processes will spin off other processes, for example with skype, you need to use
# skypeforlinux as the program name to fuzz, as that is how it shows up in ps/pgrep.
