[Cucumber-linux-security] linux (security update is available)

[Scott C. <sc...@cu...>]

  Update Information

A security update is available for linux for the following versions of
Cucumber Linux:

  * 1.0
  * 1.1

Here are the details from the Cucumber 1.1 changelog:

+----------------+
Mon May 14 18:08:17 EDT 2018
base/linux rebuilt (build 2) to enable the retpoline mitigation against the
	Spectre v2 security vulnerability (CVE-2017-5715). Starting with this
	build, the kernel-gcc package is now required to build the linux
	package. It is necessary to use the newer kernel-gcc (GCC v7.3.0)
	instead of the standard Cucumber Linux 1.1 gcc (GCC v5.3.0) because this
	mitigation requires the kernel to be compiled with a retpoline aware
	compiler, which GCC 5.3.0 is not but GCC 7.3.0 is. For more information
	see:
