# Detect CVE-2024-2961 and mitigage (tested: Ubuntu & Debian & Proxmox hosts)
# Wietse Wind 10-05-2024
# Based on the idea from https://raw.githubusercontent.com/mattaperkins/FIX-CVE-2024-2961/main/fix.sh
# ^^ Changes I made: auto detect file (several files eligible instead of one) & create back up of patched file
# Finds the right file and patches
# Safely run again to verify patch
# Run on host:
# curl https://gist.githubusercontent.com/WietseWind/9fe2eda3fece426bf873a4aeb15c4267/raw/patch.sh | bash
