Advisory, added to svn:

type: security
subject: Updated kernel-tmb packages fix security vulnerabilities
 - CVE-2017-5715
 - CVE-2017-5753
 - CVE-2017-8824
 - CVE-2017-1000410
     - kernel-tmb-4.14.18-1.mga6
description: |
  This kernel-tmb update is based on the upstream 4.14.18 and and adds some
  support for mitigating  Spectre, variant 1 (CVE-2017-5753) and as it is
  built with the retpoline-aware gcc-5.5.0-1.mga6, it now provides full
  retpoline mitigation for Spectre, variant 2 (CVE-2017-5715).

  The BPF interpreter has been used as part of the spectre 2 attack
  CVE-2017-5715. To make attacker job harder introduce BPF_JIT_ALWAYS_ON
  config option that removes interpreter from the kernel in favor of JIT-only
  mode. This is now enabled by default in Mageia kernels.

  Other security fixes in this update:

  Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies
  in the processing of incoming L2CAP commands - ConfigRequest, and
  ConfigResponse messages. This info leak is a result of uninitialized stack
  variables that may be returned to an attacker in their uninitialized state.
  By manipulating the code flows that precede the handling of these
  configuration messages, an attacker can also gain some control over which
  data will be held in the uninitialized stack variables. This can allow him
  to bypass KASLR, and stack canaries protection - as both pointers and stack
  canaries may be leaked in this manner (CVE-2017-1000410).

  The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through
  4.14.3 allows local users to gain privileges or cause a denial of service
  (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN
  state (CVE-2017-8824).

  WireGuard has been updated to 0.0.20180202

  This update also fixes the rtl8812au driver that got broken/missing in
  the upgrade to 4.14 series kernels (mga#22524).
