Xen Security Advisory (XSA) Tracker
|
|
===================================
|
|
|
|
This tracker shows whether Qubes OS is affected by any given [Xen Security Advisory (XSA)][XSA].
|
|
Shortly after a new XSA is published, we will add a new row to this tracker.
|
|
Whenever Qubes is significantly affected by an XSA, a [Qubes Security Bulletin (QSB)][QSB] is published, and a link to that QSB is added to the row for the associated XSA.
|
|
|
|
Under the "Is Qubes Affected?" column, there are two possible values: **Yes** or **No**.
|
|
|
|
* **Yes** means that the *security* of Qubes OS *is* affected.
|
|
* **No** means that the *security* of Qubes OS is *not* affected.
|
|
|
|
|
|
Important Notes
|
|
---------------
|
|
* For the purpose of this tracker, we do *not* classify mere [denial-of-service (DoS) attacks][DoS] as affecting the *security* of Qubes OS.
|
|
Therefore, if an XSA pertains *only* to DoS attacks against Qubes, the value in the "Is Qubes Affected?" column will be **No**.
|
|
* For simplicity, we use the present tense ("is affected") throughout this page, but this does **not** necessarily mean that up-to-date Qubes installations are *currently* affected by any particular XSA.
|
|
In fact, it is extremely unlikely that any up-to-date Qubes installations are vulnerable to any XSAs on this page, since patches are almost always published concurrently with QSBs.
|
|
Please read the QSB (if any) for each XSA for patching details.
|
|
* Embargoed XSAs are excluded from this tracker until they are publicly released, since the [Xen Security Policy] does not permit us to state whether Qubes is affected prior to the embargo date.
|
|
* Unused XSA numbers are included in the tracker for the sake of completeness, but they are excluded from the [Statistics] section for the sake of accuracy.
|
|
* All dates are in UTC.
