Gentoo Linux Security


1. Security in Gentoo Linux

Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. The Gentoo Linux Security Project is tasked with providing timely information about security vulnerabilities in Gentoo Linux, along with patches to secure those vulnerabilities. We work directly with vendors, end users and other OSS projects to ensure all security incidents are responded to quickly and professionally.

You can find a document describing the policy the security team follows to treat the vulnerabilities found in the Gentoo Linux distribution on the Vulnerability Treatment Policy page.

Installing a secure Gentoo system

The Gentoo Security Handbook gives information and tips for building a secure system and hardening existing systems.

Keeping your Gentoo system secure

To stay up-to-date with the security fixes you should subscribe to receive GLSAs and apply GLSA instructions whenever you have an affected package installed. Alternatively, syncing your portage tree and upgrading every package should also keep you up-to-date security-wise.

Integration of security-only updates in Portage tools is underway. In the mean time, you can try our experimental glsa-check tool (part of the gentoolkit package) to check if a specific GLSA applies to your system (-p option), list all GLSAs with applied/affected/unaffected status (-l option) or apply a given GLSA to your system (-f option).

2. Gentoo Linux Security Announcements (GLSAs)

Gentoo Linux Security Announcements are notifications that we send out to the community to inform them of security vulnerabilities related to Gentoo Linux or the packages contained in our portage repository.

Recent Advisories

For a full list of all published GLSAs, please see our GLSA index page.

How to receive GLSAs

GLSA announcements are sent to the [email protected] mailing-list, and as a RDF feed available at

3. Security Team contact information

Gentoo Linux takes security vulnerability reports very seriously. Please file new vulnerability reports on Gentoo Bugzilla and assign them to the Gentoo Security product and Vulnerabilities component. Click here to directly submit a new security vulnerability. The Gentoo Linux Security Team will ensure all security-related bug reports are responded to in a timely fashion.

If you find errors or omissions in published GLSAs, you should also file a bug in Gentoo Bugzilla in the Gentoo Security product, but with GLSA Errors component. Click here to directly submit a new GLSA bug.
