New! Plugin Severity Now Using CVSS v3
The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.
SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThe SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.
Four new speculative execution information leak issues have been identified in Intel CPUs. (bsc#1111331)
CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS)
CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS)
CVE-2018-12130: Microarchitectural Load Port Data Samling (MLPDS)
CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM)
This kernel update contains software mitigations for these issues, which also utilize CPU microcode updates shipped in parallel.

The following security bugs were fixed: CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network could use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service. (bnc#1096748).
CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. (bnc#1096748).
CVE-2016-8636: Integer overflow in the mem_check_range function in drivers/infiniband/sw/rxe/rxe_mr.c allowed local users to cause a denial of service (memory corruption), obtain sensitive information or possibly have unspecified other impact via a write or read request involving the 'RDMA protocol over infiniband' (aka Soft RoCE) technology (bnc#1024908).
CVE-2017-18174: In the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free (bnc#1080533).
CVE-2018-1091: In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path, leading to a denial of service (bnc#1087231).
CVE-2018-1120: By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which made a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks) (bnc#1093158). </pid></pid>
CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c has multiple race conditions (bnc#1133188).
CVE-2019-3882: A flaw was found in the vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS) (bsc#1131427).
CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).
CVE-2017-17741: The KVM implementation allowed attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h (bnc#1073311).
CVE-2019-9503, CVE-2019-8564: Multiple brcmfmac frame validation bypasses have been fixed (bnc#1132828, bnc#1132673).
The update package also includes non-security fixes. See advisory for details.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
