v6.7.1

v6.7.1 (2023-09-20)

Full Changelog

Security

⚠️ This release fixes a medium-severity security vulnerability. We recommend upgrading to v6.7.1 or v5.22.5.

• Affected versions: All prior versions of Elastic CI Stack (except v5.22.5). v6.7.0 and v5.22.4 contained a partial fix.
• Impact: Privilege escalation to root on Linux agent instances
• Required privileges: Users that can run user-controlled commands on agents (e.g. by pushing a branch to a repo that triggers a build with those changes)
• Attack vector: A specially crafted build can abuse the fix-buildkite-agent-builds-permissions script to run commands as root on subsequent builds
• Fix: Improved input validation and file handling #1219, #1221 (@DrJosh9000)
• Alternative workarounds: Deploy a pre-bootstrap hook to prevent execution of fix-buildkite-agent-builds-permissions during a build

Thanks to Nick Nam of Atredis Partners for reporting the vulnerability.
