GitHub Enterprise 2.11.9 January 16, 2018 Series notes · Download

The 2.11 series release notes contain important changes in this release series.

Meltdown

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.

Note on Hotpatching

The hotpatch contains an upgrade to the kernel and requires a reboot. The Meltdown attack is not fixed until a reboot is performed.
