# Security policy for GLib
* [Supported Versions](#Supported-Versions)
* [Reporting a Vulnerability](#Reporting-a-Vulnerability)
* [Security Announcements](#Security-Announcements)
* [Acknowledgements](#Acknowledgements)
## Supported Versions
Expand security policy to cover previous stable branch The goal here is to reconcile the difference between GLib's 6-month security policy and GNOME's 12-month policy (which may soon be expanded to 13 months, gnome-build-meta#731). It's strange for GLib to be an exception when the rest of GNOME supports two stable branches at a time. I'm not aware of any other GNOME project with a shorter release lifetime than GNOME itself, and it results in a situation where the previous stable version of the GNOME runtime never receives any GLib updates, since we stick with the same GLib version for the entire release and do not do security backports. But I also want to avoid creating an expectation that GLib maintainers will do a bunch of additional backporting work, so most commits should be out of scope. We can say maintainer discretion will be used to determine whether a backport to the previous stable branch is warranted. And normally, it won't be, so the goal should be no previous stable branch releases. But occasionally we might feel a CVE is important enough that a release really is warranted.

Upstream GLib only supports the most recent stable release series, the previous
stable release series, and the current development release series. Any older
stable release series are no longer supported, although they may still receive
backported security updates in long-term support distributions. Such support is
up to the distributions, though.
The previous stable release series will generally receive fixes only for high
impact security issues, at maintainer discretion. Since such issues are rare,
it's expected that there may be no backports or releases on the previous stable
branch.

Under GLib’s versioning scheme, stable release series have an *even* minor
component (for example, 2.66.0, 2.66.1, 2.68.3), and development release series
have an *odd* minor component (2.67.1, 2.69.0).

## Signed Releases
The git tags for all releases ≥2.58.0 are signed by a maintainer using
[git-evtag](https://github.com/cgwalters/git-evtag). The maintainer will use
their personal GPG key; there is currently not necessarily a formal chain of
trust for these keys. Please [create an issue](https://gitlab.gnome.org/GNOME/glib/-/issues/new)
if you would like to work on improving this.
Unsigned releases ≥2.58.0 should not be trusted. Releases prior to 2.58.0 were
not signed.

## Reporting a Vulnerability
If you think you've identified a security issue in GLib, GObject or GIO, please
**do not** report the issue publicly via a mailing list, IRC, a public issue on
the GitLab issue tracker, a merge request, or any other public venue.
Instead, report a
[*confidential* issue in the GitLab issue tracker](https://gitlab.gnome.org/GNOME/glib/-/issues/new?issue[confidential]=1),
with the “This issue is confidential” box checked. Please include as many
details as possible, including a minimal reproducible example of the issue, and
an idea of how exploitable/severe you think it is.
**Do not** provide a merge request to fix the issue, as there is currently no
way to make confidential merge requests on gitlab.gnome.org. If you have patches
which fix the security issue, please attach them to your confidential issue as
patch files.
Confidential issues are only visible to the reporter and the GLib maintainers.
As per the [GNOME security policy](https://security.gnome.org/), the next steps
are then:
* The report is triaged.
* Code is audited to find any potential similar problems.
* If it is determined, in consultation with the submitter, that a CVE is
required, the submitter obtains one via [cveform.mitre.org](https://cveform.mitre.org/).
* The fix is prepared for the development branch, and for the most recent
stable branch.
* The fix is submitted to the public repository.
* On the day the issue and fix are made public, an announcement is made on the
[public channels listed below](#Security-Announcements).
* A new release containing the fix is issued.

## Acknowledgements
This text was partially based on the
docs: Update various external links to use HEAD instead of master Update several links to allow the remote to use its configured default branch name, rather than specifying `master` as the default branch name. This will help avoid breakage if any of these projects rename their default branch in the future. Fix a few of the links where they were hitting redirects or had moved.
