Gentoo Linux Security
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

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).
