This release addresses the Meltdown (CVE-2017-5754) attack. This has been fixed in the 3.16.51-3+deb8u1 release from Debian. Please note that this patch does not address the Spectre (CVE-2017-5753 and CVE-2017-5715) vulnerability. A fix is not available for the Spectre vulnerability yet.
Internally conducted benchmarks indicate the performance impact is limited to a 2-5% increase in CPU usage on most platforms. The impact can vary depending on your usage and platform though. If you see a significant performance difference, don't hesitate to reach out to Enterprise Support.
The hotpatch contains an upgrade to the kernel and requires a reboot. The Meltdown attack is not fixed until a reboot is performed.

Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5753 and CVE-2017-5715) exploit critical vulnerabilities in modern processors. These hardware vulnerabilities allow programs to extract data which is currently processed on the same machine. This also can affect GitHub Enterprise.
The risk to GitHub Enterprise depends on the environment that it runs in. There are two main vectors of attack that need to be considered.
Given that GitHub Enterprise runs on various virtualization platforms, it's essential to update the virtualization platform where possible to mitigate any of these issues. The existing patches and fixes almost all focus on solving Meltdown. Meltdown is more straightforward to fix and most providers focus on this first.
Spectre is more complicated to exploit and also more complicated to fix. KVM for example is not vulnerable to Meltdown but is vulnerable, with a proof of concept, to Spectre which was tested by Google in the project originally (see https://googleprojectzero.blogspot.nl/2018/01/reading-privileged-memory-with-side.html). Specifically under "Reading host memory from a KVM guest". This Spectre exploit tested against a specific kernel version, but nothing implies it's impossible to adapt for other kernel versions and or other virtualization platforms.
The following Cloud and virtualization platforms have released announcements and/or fixes.
The vulnerability can also be exploited if there is code under the control of an attacker running on the same system. GitHub Enterprise has very limited support for custom code in the form of pre-receive hooks. Pre-receive hooks are limited such that administrators are the only ones who can set them up and their runtime execution is limited to 5 seconds. Both these aspects greatly limit the risk of data exposure through pre-receive hooks. As a general rule, administrators should ensure that only known and trusted pre-receive hooks are enabled on their appliance.
GitHub Enterprise is based on Debian Jessie. A fix for Meltdown is not yet available for Debian Jessie, as can be seen in the Debian CVE tracker for Meltdown. The new kernel version will be included in a future release of GitHub Enterprise and can potentially come with a performance regression. Accordingly, we recommend testing that release before putting it into production.
The primary risk for GitHub Enterprise installations is cross-guest or host <-> guest data leakage on the virtualization platform. This may be mitigated by the support cloud hosting providers, or by the suppliers of virtualization software. There is very limited risk of externally supplied software running within the appliance obtaining data from other processes, mitigated by administrators only enabling pre-receive hooks that are reviewed and trusted.

In response to CVE-2017-15361, certain SSH authentication RSA keys that were generated by some Yubikey 4 devices are vulnerable to private key factorization. Such keys are considered cryptographically weak and therefore in need of replacement. To help users avoid vulnerable keys, GitHub Enterprise has added capabilities to detect and reject them from being configured for user authentication. GitHub Enterprise now includes an administration utility, ghe-ssh-weak-fingerprints, to enable admins to list any affected keys and, optionally, perform a bulk revocation.
The affected supported versions are:
This vulnerability was found and reported internally and we have no evidence that it has been exploited in the wild.
We strongly recommend upgrading your GitHub Enterprise appliance to the latest patch release in your series, GitHub Enterprise 2.8.22, 2.9.14, 2.10.9, or 2.11.3.
