Reporting Security Issues in Qubes OS
If you believe you have found a security issue affecting Qubes OS, either directly or indirectly (e.g., the issue affects Xen in a configuration that is used in Qubes OS), then we would be more than happy to hear from you! Please send a PGP-encrypted email to the Qubes Security Team. We promise to take all reported issues seriously. If our investigation confirms that an issue affects Qubes, we will patch it within a reasonable time and release a public Qubes Security Bulletin (QSB) that describes the issue, discusses the potential impact of the vulnerability, references applicable patches or workarounds, and credits the discoverer.
Qubes security updates are obtained by updating Qubes OS.
