Security update for the Linux Kernel (Live Patch 0 for SLE 15 SP1)

Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 0 for SLE 15 SP1)
Description of the patch
This update for the Linux Kernel 4.12.14-195 fixes several issues. The following security issues were fixed: - CVE-2019-11477: Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. (bsc#1137586) - CVE-2019-11478: Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. (bsc#1137586) This update contains a regression fix for CVE-2019-11477 and CVE-2019-11478 (bsc#1140747).
