The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14218-1 advisory.

  - An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket     option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general     protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be     triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after     namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of     the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before     4.9.187. (CVE-2017-18509)

  - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an     out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)

  - Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to potentially enable denial of service of the host system via     local access. (CVE-2018-12207)

  - An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists,     related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated     user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135)

  - An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux     kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer     'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be     supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm'     device could use this flaw to crash the host kernel, resulting in a denial of service or potentially     escalating privileges on the system. (CVE-2019-14821)

  - A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost     functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A     privileged guest user able to pass descriptors with invalid length to the host when migration is underway,     could use this flaw to increase their privileges on the host. (CVE-2019-14835)

  - check_input_term in sound/usb/mixer.c in the Linux kernel through 5.2.9 mishandles recursion, leading to     kernel stack exhaustion. (CVE-2019-15118)

  - An issue was discovered in the Linux kernel before 5.1.8. There is a double-free caused by a malicious USB     device in the drivers/usb/misc/rio500.c driver. (CVE-2019-15212)

  - An issue was discovered in the Linux kernel before 5.0.14. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/usb/misc/yurex.c driver. (CVE-2019-15216)

  - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)

  - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver. (CVE-2019-15219)

  - An issue was discovered in the Linux kernel through 5.2.9. There is a NULL pointer dereference caused by a     malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver.
    (CVE-2019-15291)

  - An issue was discovered in the Linux kernel before 5.0.9. There is a use-after-free in atalk_proc_exit,     related to net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and net/appletalk/sysctl_net_atalk.c.
    (CVE-2019-15292)

  - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via     crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)

  - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS     expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)

  - A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x     through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the     upstream x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg() commit reintroduced the Spectre     vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry     picking specific commits, and because two (correctly ordered) code lines were swapped. (CVE-2019-15902)

  - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function     build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)

  - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16233)

  - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16234)

  - An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write()     properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.
    (CVE-2019-16413)

  - ax25_create in net/ax25/af_ax25.c in the AF_AX25 network module in the Linux kernel 3.16 through 5.3.2     does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-0614e2b73768. (CVE-2019-17052)

  - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel     through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket,     aka CID-e69dbd4619e7. (CVE-2019-17053)

  - atalk_create in net/appletalk/ddp.c in the AF_APPLETALK network module in the Linux kernel through 5.3.2     does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-6cc03e8aa36c. (CVE-2019-17054)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21. (CVE-2019-17055)

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - In the Android kernel in Pixel C USB monitor driver there is a possible OOB write due to a missing bounds     check. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation. (CVE-2019-9456)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2020-0044 for details.

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5866 advisory.

  - In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference     counting because of a race condition, leading to a use-after-free. (CVE-2019-6974)

  - The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. (CVE-2019-7221)

  - The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak. (CVE-2019-7222)

  - A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network     namespaces at the same time can 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. (CVE-2018-16884)

  - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the     mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an
    __blk_drain_queue() use-after-free because a certain error case is mishandled. (CVE-2018-20856)

  - The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An     attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are     believed to be vulnerable. (CVE-2019-3874)

  - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could     use this flaw to obtain sensitive information, cause a denial of service, or possibly have other     unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.
    (CVE-2019-14898)

  - In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in     fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. (CVE-2019-20054)

  - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check     the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - In the Linux kernel through 5.4.6, there is a NULL pointer dereference in     drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related     to a PHY down race condition, aka CID-f70267f379b5. (CVE-2019-19965)

  - In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which     may cause denial of service, aka CID-1d3ff0950e2b. (CVE-2019-20096)

  - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN     and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't     correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would     allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this     vulnerability is to data confidentiality. (CVE-2020-1749)

  - Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow     attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout()     failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the     htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)

  - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via     crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)

  - An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in     net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain     failure case involving TPACKET_V3, aka CID-b43d1f9f7067. (CVE-2019-20812)

  - A flaw was found in the Linux kernels implementation of the invert video code on VGA consoles when a     local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds     write to occur. This flaw allows a local user with access to the VGA console to crash the system,     potentially escalating their privileges on the system. The highest threat from this vulnerability is to     data confidentiality and integrity as well as system availability. (CVE-2020-14331)

  - fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer     dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka     CID-09ba3bc9dd15. (CVE-2019-18885)

  - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4     bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of     service. (CVE-2020-10769)

  - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing. (CVE-2020-10751)

  - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An     attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations     before the required authentication process has completed. This could lead to different denial-of-service     scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already     existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge     Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)

  - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)

  - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/media/usb/siano/smsusb.c driver. (CVE-2019-15218)

  - An issue was discovered in drivers/net/ethernet/arc/emac_main.c in the Linux kernel before 4.5. A use-     after-free is caused by a race condition between the functions arc_emac_tx and arc_emac_tx_clean.
    (CVE-2016-10906)

  - The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local     users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.
    (CVE-2017-8925)

  - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file     system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash     the system if the directory exists. The highest threat from this vulnerability is to system availability.
    (CVE-2020-14314)

  - sound/core/seq_device.c in the Linux kernel before 4.13.4 allows local users to cause a denial of service     (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a     crafted USB device. (CVE-2017-16528)

  - The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows     local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer     underflow. (CVE-2017-8924)

  - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to     improper locking. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android     ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)

  - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function     build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)

  - A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an     attacker with local access to crash the system. (CVE-2020-10720)

  - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers     to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c     instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)

  - The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete     permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap     rbd block devices, aka CID-f44d04e696fe. (CVE-2020-25284)

  - A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be     used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified     other impact, aka CID-17743798d812. (CVE-2020-25285)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5715 advisory.

  - The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to     prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive     information, cause a denial of service, or possibly have unspecified other impact by triggering a race     condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c,     fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c. (CVE-2019-11599)

  - The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable     to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event     frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This     vulnerability can be exploited with compromised chipsets to compromise the host, or when used in     combination with CVE-2019-9503, can be used remotely. In the worst case scenario, by sending specially-     crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a     vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.
    (CVE-2019-9500)

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

    (CVE-2019-14896)

  - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via     crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)

  - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking     vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on     a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value     remains the same starting from boot time, and can be inferred by an attacker. This affects     net/core/flow_dissector.c and related code. (CVE-2019-18282)

  - The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors     in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka     CID-4ea99936a163. (CVE-2019-19767)

  - Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543)

  - ** DISPUTED ** An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in     arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because     it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will.
    (CVE-2020-12768)

  - A memory leak in the mlx5_fpga_conn_create_cq() function in     drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c in the Linux kernel before 5.3.11 allows attackers to     cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures, aka     CID-c8c2a057fdc7. (CVE-2019-19045)

  - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     alloc_page() failures, aka CID-b4b814fec1a5. (CVE-2019-19058)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

The Linux Kernel KVM hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-11135:
Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233:
