If you find a vulnerability in our software, please send the email to "tatsuhiro.t at gmail dot com" about its details instead of submitting issues on github issue page. It is a standard practice not to disclose vulnerability information publicly until a fixed version is released, or mitigation is worked out. In the future, we may setup a dedicated mail address for this purpose.
If we identify that the reported issue is really a vulnerability, we open a new security advisory draft using GitHub security feature and discuss the mitigation and bug fixes there. The fixes are committed to the private repository.
We write the security advisory and get CVE number from GitHub privately. We also discuss the disclosure date to the public.
We make a new release with the fix at the same time when the vulnerability is disclosed to public.
At least 7 days before the public disclosure date, we will post
security advisory (which includes all the details of the vulnerability
and the possible mitigation strategies) and the patches to fix the
issue to distros@openwall
mailing list. We also open a new issue on nghttp2 issue tracker which notifies that the
upcoming release will have a security fix. The
SECURITY label is
attached to this kind of issue.
Before few hours of new release, we merge the fixes to the master branch (and/or a release branch if necessary) and make a new release. Security advisory is disclosed on GitHub. We also post the vulnerability information to oss-security mailing list.
