Security update for the Linux Kernel (Live Patch 4 for SLE 12 SP3)

This update for the Linux Kernel 4.4.90-6_12 fixes several issues.

The following security issues were fixed:

  • CVE-2017-17712: The raw_sendmsg() function had a race condition that lead to uninitialized stack pointer usage. This allowed a local user to execute code and gain privileges (bsc#1073230).
  • CVE-2017-16939: The XFRM dump policy implementation 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).

The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11 allows 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.

The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel through 4.14.6 has a race condition in inet->hdrincl that leads to uninitialized stack pointer usage; this allows a local user to execute code and gain privileges.
