openSUSE Security Update : the Linux Kernel (openSUSE-2017-1159)

Medium Nessus Plugin ID 104074

Synopsis

The remote openSUSE host is missing a security update.

Description

The openSUSE Leap 42.2 Kernel was updated to 4.4.90 to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to arch/x86/kvm/vmx.c and virt/kvm/eventfd.c (bnc#1058038).

- CVE-2017-14489: The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel allowed local users to cause a denial of service (panic) by leveraging incorrect length validation (bnc#1059051).

- CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410).

- CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the 'CR8-load exiting' and 'CR8-store exiting' L0 vmcs02 controls exist in cases where L1 omits the 'use TPR shadow' vmcs12 control, which allowed KVM L2 guest OS users to obtain read and write access to the hardware CR8 register (bnc#1058507).
