Security Issues

If you think that an issue with libvirt may have security implications, please do not publicly report it in the bug tracker, mailing lists, or irc. Libvirt has a dedicated process for handling (potential) security issues that should be used instead. So if your issue has security implications, ignore the rest of this page and follow the security process instead.

Subscribe to just this if you want to be notified of new releases, without subscribing to either of the other mailing lists.

Patches with explanations and provided as attachments are really appreciated, and should be directed to the development mailing list for review and discussion. Wherever possible, please generate the patches by using git format-patch in a git repository clone.
