Disclosure Policy

RubyGems and follow a 5 step disclosure policy:

  1. Security report received and is assigned a primary handler. This person will coordinate the fix and release process.
  2. Problem is confirmed and, a list of all affected versions is determined. Code is audited to find any potential similar problems.
  3. Fixes are prepared for all releases which are still supported. These fixes are not committed to the public repository but rather held locally pending the announcement.
  4. A suggested embargo date for this vulnerability is chosen.
  5. On the embargo date, the rubygems-developers mailing list is sent an announcement. This will include patches for all versions still under support. The changes are pushed to the public repository and new gems released to rubygems. At least 6 hours after the mailing list is notified, a copy of the advisory will be published on the blog.

This process can take some time, especially when coordination is required with maintainers of other projects. Every effort will be made to handle the bug in as timely a manner as possible, however it’s important that we follow the release process above to ensure that the disclosure is handled in a consistent manner.

Receiving Security Updates

The best way to receive all the security announcements is to subscribe to the rubygems-developers mailing list.

No one outside the core team or the initial reporter will be notified prior to the lifting of the embargo. We regret that we cannot make exceptions to this policy for high traffic or important sites, as any disclosure beyond the minimum required to coordinate a fix could cause an early leak of the vulnerability.
