[OS Check] INFO: Ubuntu 22.04 detected
[Apport Check] INFO: Apport version 2.32.0 installed
[Version Check] VULNERABLE: Version 2.32.0 is vulnerable
[Core Pattern] INFO: Apport is configured as core dump handler

SUMMARY
============================================================
[!] YOUR SYSTEM APPEARS TO BE VULNERABLE TO CVE-2025-5054
Recommended actions:
1. Update Apport to the latest version:
sudo apt update && sudo apt upgrade apport
2. As a temporary mitigation, disable SUID core dumps:
sudo sysctl fs.suid_dumpable=0
echo 'fs.suid_dumpable=0' | sudo tee -a /etc/sysctl.conf
3. Consider disabling Apport temporarily if updates are not available:
sudo systemctl stop apport.service
sudo systemctl disable apport.service
