An update that solves two vulnerabilities and has one errata is now available.
Description:
This update for the Linux Kernel 3.12.61-52_101 fixes several issues.
The following security issues were fixed:
- CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c 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-2017-15649: net/packet/af_packet.c allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free (bsc#1064392).
