Security update for the linux kernel (live patch 27 for sle 12 sp2)
SUSE-SLE-SERVER-12-SP2-2019-793
This update for the Linux Kernel 4.4.121-92_101 fixes several issues. The following security issues were fixed: - CVE-2019-9213: Expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bsc#1128378). - CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124734). - CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free (bsc#1124729). - 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 up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host (bsc#1107832). - CVE-2018-5390: The Linux kernel could be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which could have led to a denial of service (bsc#1102682).
