Security update for the Linux Kernel (Live Patch 25 for SLE 12 SP3)

This update for the Linux Kernel 4.4.178-94_91 fixes several issues.

The following security issues were fixed:

  • CVE-2019-14835: A buffer overflow flaw was found in the way vhost functionality, that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host (bsc#1151021).
  • CVE-2017-18379: Fixed an out of boundary access that happened in drivers/nvme/target/fc.c (bsc#1145604).

Описание

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
