Information about Meltdown and Spectre vulnerability fixes |

2020-07-15 |
Last update 26. June. at 3:00pm CET
(this table reflects the situation at a given moment and is constantly evolving.)
As we communicated, OVH has been informed of the Spectre (CVE-2017-5753 and CVE-2017-5715) and Meltdown (CVE-2017-5754) security vulnerabilities, making a large part of computer equipment in operation vulnerable to potential attacks, particularly those equipped with Intel CPUs.
Our technical teams are currently continuing to work on securing OVH infrastructures in order to minimize the exposure of your services to these vulnerabilities.
Restarting of some services has already begun, so that we can apply the first tested and approved stability patches to our systems, both in the operating systems of the machines and their kernel as well as in the microcode.
Some services, which are entirely managed by OVH, will not require any manipulation on your part: Domains, Metrics and Logs Data Platform, xDSL, VoIP, DBaaS, OVH Load Balancer, vRack, Exchange, MX Plan, Web Hosting, Cloud Desktop, VDI, CDN, Swift, CEPH, NAS-HA, Public Cloud Storage and Public Cloud Archive.
OVH is working to secure the infrastructures concerned, applying the patches provided by the operating system and motherboard vendors as they become available. Some operations require a reboot of the machine, which could cause an interruption of service for a short time.
Securing certain other services such as dedicated servers, Public Cloud instances, VPS or Private Cloud will require additional action on your part, consisting of applying the recommended update of the operating system vendor of your servers.
Here is :
- General information about these vulnerabilities ;
- A detailled list of all OVH products and all actions in progress and/or actions you need to do (please read carefully this section)
To help you, we also offer you a non-exhaustive table listing the updates available for the main versions of the operating systems.

Meltdown *** Rogue Data Cache Load Meltdown (CVE-2017-5754) |
| Linux |
Status : DONE Most distributions have recompiled their Kernel using LFENCE instruction. Softwares need to be recompiled with a patched compiler using LFENCE instruction to stop speculation. |
Mitigation 1: IN PROGRESS Two conditions to be protected, A and B: A) boot the OS with the new microcodes to activate new flags in CPU (the SPEC_CTRL and PRED_CMD MSRs). Two ways to do this: Option.1) charge microcode after BIOS and at the very beginning of kernel boot. The new microcode has to be loaded to the CPU each time the OS starts. Option.2) upgrade BIOS, so BIOS will load new microcode in CPU, before the OS boot phase. Once the BIOS is upgraded, the system will load with new microcode automatically. IN PROGRESS OVH already released any microcode and BIOS that vendors provided. B) Install a kernel that is integrating the new IBRS and IBPB patches that are using the new CPU MSR, made available by the microcode update in A) to successfully mitigate the vulnerability. On Linux, those patches have been integrated in latest kernels (4.14.14 as well as 4.9.77), and they have been compiled with a GCC with retpoline support. DONE
Openstack KVM/Qemu:
Mitigation 2: DONE Patch compilers to avoid any indirect jump and use a static trampoline (aka retpoline) gcc have a pending patch to introduce this feature. But if you recompile the kernel with this, it'll fix only the kernel itself. If the kernel is fixed, you'll not be able to read kernel memory, but you'll still be able to read other process memory. All software have to be recompiled with mitigation to be secured. https://lkml.org/lkml/2018/1/3/780 https://googleprojectzero.blogspot.fr/2018/01/reading-privileged-memory-with-side.html GCC patches for retpoline: http://git.infradead.org/users/dwmw2/gcc-retpoline.git/shortlog/refs/heads/gcc-7_2_0-retpoline-20171219 |
Status: DONE Kernel patch to isolate kernel space and user space (aka KPTI). It is available in kernel vanilla 4.14.11+, 4.9.75+, 4.4.110+ Linux distributions are backporting the patches themselves in their own kernel versions, refer to our list of patches available per distribution for more information. |
| Windows |
Status: DONE Softwares need to be recompiled with a patched compiler using LFENCE instruction to stop speculation. |
Two conditions to be protected, A and B:
A) boot the OS with the new microcodes to activate new flags in CPU (the SPEC_CTRL and PRED_CMD MSRs), there are 2 ways to do this:
A.Option.1) charge microcode after BIOS and at the very beginning of kernel boot. In progress with Windows. A.Option.2) upgrade BIOS, so BIOS will load new microcode in CPU, before the OS boot phase. Once the BIOS is upgraded, the system will load with new microcode automatically. Works with all OS. IN PROGRESS OVH already released any microcode and BIOS that vendors provided.
B) Install the latest Windows security updates that integrates the patches that are using the new CPU MSR, made available by the microcode update in A) to successfully mitigate the vulnerability. Note that you must also have a compatible Antivirus for this security install to be available, refer to the OS matrix for details.
