Public release. ISSUE DESCRIPTION ================= Page table manipulation operations for PV guests can take significant amounts of time, as they require all present branches to have their type (and thus contents) verified. While the most frequently used operations had been made preemptible in the past, some code paths involving potentially deep page table traversal were still trying to do their entire work in a single step. IMPACT ====== Malicious or buggy PV guest kernels can mount a denial of service attack affecting the whole system. VULNERABLE SYSTEMS ================== All Xen versions are vulnerable. The vulnerability is only exposed by PV guests. MITIGATION ========== Running only HVM guests, or PV guests with trusted kernels, will avoid this vulnerability. RESOLUTION ========== Applying the appropriate attached patch series resolves this issue. xsa45-4.1-*.patch Xen 4.1.x xsa45-4.2-*.patch Xen 4.2.x xsa45-unstable-*.patch xen-unstable $ sha256sum

2 Several long latency operations are not preemptible UPDATES IN VERSION 2 ==================== Patches for xen-unstable refreshed to apply on top of xen.git#staging commit 9626d1c1. Public release. ISSUE DESCRIPTION ================= Page table manipulation operations for PV guests can take significant amounts of time, as they require all present branches to have their type (and thus contents) verified. While the most frequently used operations had been made preemptible in the past, some code paths involving potentially deep page table traversal were still trying to do their entire work in a single step. IMPACT ====== Malicious or buggy PV guest kernels can mount a denial of service attack affecting the whole system. VULNERABLE SYSTEMS ================== All Xen versions are vulnerable. The vulnerability is only exposed by PV guests. MITIGATION ========== Running only HVM guests, or PV guests with trusted kernels, will avoid this vulnerability. RESOLUTION ========== Applying the appropriate attached patch series resolves this issue. xsa45-4.1-*.patch Xen 4.1.x xsa45-4.2-*.patch Xen 4.2.x xsa45-unstable-*.patch xen-unstable $ sha256sum

2 VT-d interrupt remapping source validation flaw for bridges UPDATES IN VERSION 2 ==================== Public release. ISSUE DESCRIPTION ================= Interrupt remapping table entries for MSI interrupts set up by bridge devices did not get any source validation set up on them, allowing misbehaving or malicious guests to inject interrupts into the domain owning the bridges. In a typical Xen system bridge devices are owned by domain 0, leaving it vulnerable to such an attack. Such a DoS is likely to have an impact on other guests running in the system. IMPACT ====== A malicious domain, given access to a device which bus mastering capable, can mount a denial of service attack affecting the whole system. VULNERABLE SYSTEMS ================== Xen version 4.0 onwards is vulnerable. Only systems using Intel VT-d for PCI passthrough are vulnerable. Any domain which is given access to a PCI device that is bus mastering capable can take advantage of this vulnerability.

ISSUE DESCRIPTION ================= Interrupt remapping table entries for MSI interrupts set up by bridge devices did not get any source validation set up on them, allowing misbehaving or malicious guests to inject interrupts into the domain owning the bridges. In a typical Xen system bridge devices are owned by domain 0, leaving it vulnerable to such an attack. Such a DoS is likely to have an impact on other guests running in the system. IMPACT ====== A malicious domain, given access to a device which bus mastering capable, can mount a denial of service attack affecting the whole system. VULNERABLE SYSTEMS ================== Xen version 4.0 onwards is vulnerable. Only systems using Intel VT-d for PCI passthrough are vulnerable. Any domain which is given access to a PCI device that is bus mastering capable can take advantage of this vulnerability.

ISSUE DESCRIPTION ================= The qemu guest agent creates files with insecure permissions when started in daemon mode. IMPACT ====== The qemu guest agent is not used by default in Xen systems. If it is used in a particular guest, unprivileged guest processes might be able to escalate their privilege to that of the guest. VULNERABLE SYSTEMS ================== We are not aware of any Xen installations using the qemu guest agent. However, the program is built and installed (as the executable `qemu-ga') as part of the Xen management tools by the Xen build system. It is possible that a system administrator, or downstream system integrator, might have arranged to execute qemu-ga. If you have not taken steps to run qemu-ga, you are not vulnerable. MITIGATION ========== Disabling the guest agent will eliminate the vulnerability. RESOLUTION ========== Patches to resolve this problem are available from the upstream qemu project via the usual channels. The Xen Project Security Team do not intend to provide or distribute patches for this vulnerability.

ISSUE DESCRIPTION ================= The qemu guest agent creates files with insecure permissions when started in daemon mode. IMPACT ====== The qemu guest agent is not used by default in Xen systems. If it is used in a particular guest, unprivileged guest processes might be able to escalate their privilege to that of the guest. VULNERABLE SYSTEMS ================== We are not aware of any Xen installations using the qemu guest agent. However, the program is built and installed (as the executable `qemu-ga') as part of the Xen management tools by the Xen build system. It is possible that a system administrator, or downstream system integrator, might have arranged to execute qemu-ga. If you have not taken steps to run qemu-ga, you are not vulnerable. MITIGATION ========== Disabling the guest agent will eliminate the vulnerability. RESOLUTION ========== Patches to resolve this problem are available from the upstream qemu project via the usual channels. The Xen Project Security Team do not intend to provide or distribute patches for this vulnerability. DETAILS ======= At the time of writing the information we have about this vulnerability is as follows: Subject: [PATCH] qga: set umask 0077 when daemonizing (CVE-2013-2007) The qemu guest agent creates a bunch of files with insecure permissions when started in daemon mode.

On April 14th, we started a discussion on naming list conventions, which then became a proposal for Mailing List Conventions. There seems to be no controversy, thus it is time to vote using the voting form above.

Governance Proposals for Review

Xen Security Problem Response Process v2

In the last update on the security problem response process, we promised a vote in mid-January. Near the end of the window, some changes were proposed, and we were somewhat sidetracked with launching Xen as a Linux Foundation Collaborative Project.

As this process impacts many Xen users, we feel that it is prudent to run through a final week of community review (closing on Monday May 20th), followed by a formal vote by maintainers, committers and the project lead of the Hypervisor project a week later. Review comments are to be posted in response to this thread. The proposal can be found here.

For Vote: Dates and Locations for 2014 Events

As it is very hard to book event space on short notice, I wanted to ask you all where to hold Xen Project user and developer events in 2014. Earlier this year, there was a debate whether we should rotate Xen Events around the globe. The answer was a very strong yes. As we have a Hackathon and Xen Developer Summit in Europe this year, Europe will not be an option for a developer event in 2014.

Rather than creating a voting form, I decided to use the voting feature on the new Xen Project website. To vote, you need to create an account. If you have difficulties, let me know. The poll is here. The vote will stay open until the middle of June.

ISSUE DESCRIPTION ================= The Python bindings for the xc_vcpu_setaffinity call do not properly check their inputs. Systems which allow untrusted administrators to configure guest vcpu affinity may be exploited to trigger a buffer overrun and corrupt memory. IMPACT ====== An attacker who is able to configure a specific vcpu affinity via a toolstack which uses the Python bindings is able to exploit this issue. Exploiting this issue leads to memory corruption which may result in a DoS against the system by crashing the toolstack. The possibility of code execution (privilege escalation) has not been ruled out. The xend toolstack passes a cpumap to this function without sanitization. xend allows the cpumap to be configured via the guest configuration file or the SXP/XenAPI interface. Normally these interfaces are not considered safe to expose to non-trusted parties. However systems which attempt to allow guest administrator control of VCPU affinity in a safe way via xend may expose this issue. VULNERABLE SYSTEMS ================== Xen version 4.0 and later contain this flaw. Only systems which allow the specification of cpu affinity masks by untrusted guest administrators are vulnerable. Normally the cpu affinity is specified by the host administrator as part of the guest configuration; there is then no vulnerability. Only systems which use the libxc Python bindings, are vulnerable. Toolstacks which do not use Python, such as xl or xapi, are not vulnerable. MITIGATION ========== Not allowing untrusted guest administrators to configure VCPU affinity will avoid exposure. Where possible switching to a toolstack which does not use Python will also avoid exposure to this vulnerability. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. xsa56.patch Xen 4.1.x, Xen 4.2.x, xen-unstable $ sha256sum xsa56*.patch a691c5f5332a42c0d38ddb4dc037eb902f01ba31033b64c47d02909a8de0257d xsa56.patch $ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBAgAGBQJRlk9eAAoJEIP+FMlX6CvZIOMIAJFcMxxknbjo9oT9Plv8I9TA agEEaUV/cbZTUWHCdGLj6G8kHp4Td8mfKzHy9ZKlNn0GJ0vgezi08enxjgjSlloG 7KAsLAYYlrwjtSmu74CC48EDKF5KTy3xhxGIMT14fJAyDUAStwgHHZbcE8dNvaXk sfygb5epW+ZzQBkOxhKQkNDt5yoGVZ+Zb4Z/pmBXb+e8SVx+4i005HPuB8aIFowi 1nlbo2cSkFj6/NP5olhDQOYM5LEqzO8GPgHjTXJmIoTxA0Zuu4P53qjLsose5DCy 4OQY1v76lMP419t0I3UwA/KUott3PaUc3kzE24/3AmVxsh27k6cyVxovV4jsvf0= =5dzZ -----END PGP SIGNATURE----- --=separator Content-Type: application/octet-stream;
