Reporting security issues in Qubes OS
If you've discovered 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! 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. Please use the Qubes security team PGP key to encrypt your email to this address:
security at qubes-os dot org
This key is signed by the Qubes Master Signing Key. Please see verifying signatures for information about how to authenticate these keys.
Security updates
Qubes security updates are obtained by updating Qubes OS.
Qubes security team
The Qubes security team (QST) is the subset of the core team that is responsible for ensuring the security of Qubes OS and the Qubes OS Project. In particular, the QST is responsible for:
- Responding to reported security issues
- Evaluating whether XSAs affect the security of Qubes OS
- Writing, applying, and/or distributing security patches to fix vulnerabilities in Qubes OS
- Writing, signing, and publishing Qubes security bulletins (QSBs)
- Writing, signing, and publishing Qubes canaries
- Generating, safeguarding, and using the project's PGP keys
As a security-oriented operating system, the QST is fundamentally important to Qubes, and every Qubes user implicitly trusts the members of the QST by virtue of the actions listed above.
