Description:

This update for the Linux Kernel 4.4.59-92_17 fixes several issues.

The following security issues were fixed:

  • CVE-2017-1000405: Problematic use of pmd_mkdirty() in the touch_pmd() function allowed users to overwrite read-only huge pages (e.g. the zero huge page and sealed shmem files) (bsc#1070307).
  • CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages (bsc#1069708).
  • CVE-2017-10661: Race condition in fs/timerfd.c allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bsc#1053153).

This non-security issue was fixed:

  • bsc#1062847: Enable proper shut down if NIC teaming is enabled
