Security update for the Linux Kernel (Live Patch 0 for SLE 12 SP4)
This update for the Linux Kernel 4.12.14-94_41 fixes one issue.
The following security issue was fixed:
- CVE-2018-16884: A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time could make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bsc#1119947).

An attacker may cause a denial of service condition by sending specially crafted IP fragments. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bsc#1103098).
Security update for the Linux Kernel (Live Patch 17 for SLE 12 SP3)

- CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash

The following security issues were fixed:
- CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682).
- CVE-2018-1000026: Fixed an insufficient input validation in bnx2x network card driver that can result in DoS via very large, specially crafted packet to the bnx2x card due to a network card firmware assertion that will take the card offline (bsc#1096723).
- CVE-2018-10938: Fixed an infinite loop in the cipso_v4_optptr() function leading to a denial-o
Security update for the Linux Kernel (Live Patch 16 for SLE 12 SP2)
This update for the Linux Kernel 4.4.103-92_53 fixes several issues.
The following security issues were fixed:
- CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system (bsc#1099306).
- CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which lead to out-of-bounds access in the show_timer function (called w
Security update for the Linux Kernel (Live Patch 8 for SLE 12 SP3)
This update for the Linux Kernel 4.4.114-94_11 fixes several issues.
The following security issue was fixed:
- CVE-2018-3665: System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially have allowed a local process to infer data from another process via a speculative execution side channel (bsc#1090338, bsc#1096740).
