MGASA-2018-0374 - Updated kernel-tmb packages fix security vulnerabilities

Publication date: 14 Sep 2018
URL: https://advisories.mageia.org/MGASA-2018-0374.html
Type: security
Affected Mageia releases: 6
CVE: CVE-2018-6554,
     CVE-2018-6555

This kernel-tmb update is based on the upstream 4.14.69 and adds additional
fixes for the L1TF and Spectre security issues. It also fixes atleast
the following security issues:

Memory leak in the irda_bind function in net/irda/af_irda.c and later in
drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows
local users to cause a denial of service (memory consumption) by repeatedly
binding an AF_IRDA socket (CVE-2018-6554).

The irda_setsockopt function in net/irda/af_irda.c and later in
drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows
local users to cause a denial of service (ias_object use-after-free and
system crash) or possibly have unspecified other impact via an AF_IRDA
socket (CVE-2018-6554).

Other fixes in this update:
* WireGuard has been updated to 0.0.20180904
* all SPI_INTEL_SPI config options have been disable to prevent a potential
  bios corrupting bug (mga#23560)

For other changes in this update, see the referenced changelogs.
