Security update for Linux Kernel Live Patch 19 for SLE 12 SP1
This update for the Linux Kernel 3.12.74-60_64_54 fixes several issues. The following security bugs were fixed: - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.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 inet_csk_clone_lock function in net/ipv4/inet_connection_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).
