Description Arvid Requate univentionstaff 2018-01-30 10:27:26 CET 
We should backport Kernel 4.9.78 to UCS 4.1-5

+++ This bug was initially created as a clone of Bug #46029 +++

* cpu: speculative execution bounds-check bypass (CVE-2017-5753)
* cpu: speculative execution branch target injection (CVE-2017-5715)CVE-2017-5715

Will probably require this:
- linux kernel update
- µcode update for Intel and AMD
- gcc update
- qemu update
- libvirtupdate

After that backport for UCS-4.1

+++ This bug was initially created as a clone of Bug #45981 +++
Comment 1 Arvid Requate univentionstaff 2018-01-30 10:59:37 CET 
8e7c4cb: Advisories, copied from branch 4.2-3 and adjusted:

* linux.yaml
* univention-kernel-image-signed.yaml
* univention-kernel-image.yaml

Manual package update and reboot looked good:
* UCS 4.1-5 VM amd64
  > Spectre V2 mitigation: Mitigation: Full generic retpoline
* UCS 4.1-5 VM i386
  > Spectre V2 mitigation: Filling RSB on context switch
  > Spectre V2 mitigation: Mitigation: Full generic retpoline

Updated via univention-install univention-kernel-image
Comment 2 Felix Botner univentionstaff 2018-01-30 12:02:32 CET 
OK - amd64/i386 (4.1-5 with ext updates)
OK - univention-install univention-kernel-image with 4.2-3 repo updates linux,
     univention-kernel-image and univention-kernel-image-signed
OK - reboot
OK - YAML files
