I'm a security researcher on the GitHub Security Lab team. I try to help make open source software more secure by searching for vulnerabilities and working with maintainers to get them fixed.

Privilege escalation with polkit: How to get root on Linux with a seven-year-old bug

polkit is a system service installed by default on many Linux distributions. It’s used by systemd, so any Linux distribution that uses systemd also uses polkit. As a member of GitHub Security Lab, my job is to help improve the security of open source software by finding and reporting vulnerabilities. A few weeks ago, I found a privilege escalation vulnerability in polkit.
