This update for the Linux Kernel 3.12.74-606451 fixes several issues.
The following security bugs were fixed:
CVE-2017-1000112: Prevent a race condition in net-packet code that could have been exploited by unprivileged users to gain root access (bsc#1052368).
CVE-2017-9242: The _ip6appenddata function in net/ipv6/ip6output.c in the Linux kernel was too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bsc#1038564, bsc#1042892).
CVE-2017-8890: The inetcskclonelock function in net/ipv4/inetconnection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bsc#1038564).
