The remote NewStart CGSL host, running version MAIN 6.01, has kernel packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the Linux kernel's NFS     implementation, all versions 3.x and all versions 4.x up     to 4.20. An attacker, who is able to mount an exported     NFS filesystem, is able to trigger a null pointer     dereference by using an invalid NFS sequence. This can     panic the machine and deny access to the NFS server. Any     outstanding disk writes to the NFS server will be lost.
    (CVE-2018-16871)

  - 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)

  - 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)

  - 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)

  - An issue was discovered in net/ipv4/sysctl_net_ipv4.c in     the Linux kernel before 5.0.11. There is a     net/ipv4/tcp_input.c signed integer overflow in     tcp_ack_update_rtt() when userspace writes a very large     integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading     to a denial of service or possibly unspecified other     impact, aka CID-19fad20d15a6. (CVE-2019-18805)

  - 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)

  - ** DISPUTED ** A memory leak in the     nl80211_get_ftm_responder_stats() function in     net/wireless/nl80211.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service     (memory consumption) by triggering nl80211hdr_put()     failures, aka CID-1399c59fa929. NOTE: third parties     dispute the relevance of this because it occurs on a     code path where a successful allocation has already     occurred. (CVE-2019-19055)

  - A memory leak in the bnxt_re_create_srq() function in     drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial     of service (memory consumption) by triggering copy to     udata failures, aka CID-4a9d46a9fe14. (CVE-2019-19077)

  - In the Linux kernel before 5.3.9, there are multiple     out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers,     aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c,     drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c,     drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-     microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - In the Linux kernel before 5.3.11, there is an info-leak     bug that can be caused by a malicious USB device in the     drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka     CID-f7a1337f0d29. (CVE-2019-19534)

  - 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)

  - A memory leak in the kernel_read_file function in     fs/exec.c in the Linux kernel through 4.20.11 allows     attackers to cause a denial of service (memory     consumption) by triggering vfs_read failures.
    (CVE-2019-8980)

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem in versions before 5.7. This     flaw occurs while importing the Commercial IP Security     Option (CIPSO) protocol's category bitmap into the     SELinux extensible bitmap via the'     ebitmap_netlbl_import' routine. While processing the     CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of service.
    (CVE-2020-10711)

  - In the Linux kernel through 5.6.7 on the s390 platform,     code execution may occur because of a race condition, as     demonstrated by code in enable_sacf_uaccess in     arch/s390/lib/uaccess.c that fails to protect against a     concurrent page table upgrade, aka CID-3f777e19d171. A     crash could also occur. (CVE-2020-11884)

  - An issue was discovered in the Linux kernel before     5.6.5. There is a use-after-free in block/bfq-iosched.c     related to bfq_idle_slice_timer_body. (CVE-2020-12657)

  - A flaw was discovered in the way that the KVM hypervisor     handled instruction emulation for an L2 guest when     nested virtualisation is enabled. Under some     circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be     inaccessible to the L2 guest. (CVE-2020-2732)

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

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1567 advisory.

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

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In the tun subsystem in the Linux kernel before     4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a     denial of service (NULL pointer dereference and panic)     via an ioctl(TUNSETIFF) call with a dev name containing     a / character. This is similar to     CVE-2013-4343.(CVE-2018-7191)

  - A memory leak in the crypto_report() function in     crypto/crypto_user_base.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service     (memory consumption) by triggering crypto_report_alg()     failures, aka CID-ffdde5932042.(CVE-2019-19062)

  - An issue was discovered in net/ipv4/sysctl_net_ipv4.c     in the Linux kernel before 5.0.11. There is a     net/ipv4/tcp_input.c signed integer overflow in     tcp_ack_update_rtt() when userspace writes a very large     integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading     to a denial of service or possibly unspecified other     impact, aka CID-19fad20d15a6.(CVE-2019-18805)

  - In the Linux kernel before 5.0, a memory leak exists in     sit_init_net() in net/ipv6/sit.c when register_netdev()     fails to register sitn->fb_tunnel_dev, which may cause     denial of service, aka     CID-07f12b26e21a.(CVE-2019-16994)

  - An issue was discovered in the Linux kernel before     5.0.6. There is a memory leak issue when idr_alloc()     fails in genl_register_family() in     net/netlink/genetlink.c.(CVE-2019-15921)

  - 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)

  - An issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9.
    XFS partially wedges when a chgrp fails on account of     being out of disk quota. xfs_setattr_nonsize is failing     to unlock the ILOCK after the xfs_qm_vop_chown_reserve     call fails. This is primarily a local DoS attack     vector, but it might result as well in remote DoS if     the XFS filesystem is exported for instance via     NFS.(CVE-2019-15538)

  - 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)

  - ** DISPUTED ** An issue was discovered in ip_ra_control     in net/ipv4/ip_sockglue.c in the Linux kernel through     5.1.5. There is an unchecked kmalloc of new_ra, which     might allow an attacker to cause a denial of service     (NULL pointer dereference and system crash). NOTE: this     is disputed because new_ra is never used if it is     NULL.(CVE-2019-12381)

  - ** DISPUTED ** An issue was discovered in     ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux     kernel through 5.1.5. There is an unchecked kmalloc of     new_ra, which might allow an attacker to cause a denial     of service (NULL pointer dereference and system crash).
    NOTE: This has been disputed as not an     issue.(CVE-2019-12378)

  - 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)

  - 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)

  - 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 was found in the Linux kernel's NFS     implementation, all versions 3.x and all versions 4.x     up to 4.20. An attacker, who is able to mount an     exported NFS filesystem, is able to trigger a null     pointer dereference by using an invalid NFS sequence.
    This can panic the machine and deny access to the NFS     server. Any outstanding disk writes to the NFS server     will be lost.(CVE-2018-16871)

  - An issue was found in the Linux kernel ipv6     implementation of GRE tunnels which allows a remote     attacker to trigger an out-of-bounds access. At this     time we understand no trust barrier has been crossed     and there is no security implications in this     flaw.(CVE-2017-5897)

  - A flaw was found in the Linux kernel's 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). Versions 3.10, 4.14 and 4.18 are     vulnerable.(CVE-2019-3882)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):Heap-based buffer overflow     in the udf_load_logicalvol function in fs/udf/super.c     in the Linux kernel before 3.4.5 allows remote     attackers to cause a denial of service (system crash)     or possibly have unspecified other impact via a crafted     UDF filesystem.(CVE-2012-3400)The     mmc_ioctl_cdrom_read_data function in     drivers/cdrom/cdrom.c in the Linux kernel through 3.10     allows local users to obtain sensitive information from     kernel memory via a read operation on a malfunctioning     CD-ROM drive.(CVE-2013-2164)The     sctp_sf_do_5_2_4_dupcook function in     net/sctp/sm_statefuns.c in the SCTP implementation in     the Linux kernel before 3.8.5 does not properly handle     associations during the processing of a duplicate     COOKIE ECHO chunk, which allows remote attackers to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unspecified other impact     via crafted SCTP traffic.(CVE-2013-2206)The (1)     get_user and (2) put_user API functions in the Linux     kernel before 3.5.5 on the v6k and v7 ARM platforms do     not validate certain addresses, which allows attackers     to read or modify the contents of arbitrary kernel     memory locations via a crafted application, as     exploited in the wild against Android devices in     October and November 2013.(CVE-2013-6282)An issue was     discovered in the Linux kernel before 4.20. There is a     race condition in smp_task_timedout() and     smp_task_done() in drivers/scsi/libsas/sas_expander.c,     leading to a use-after-free.(CVE-2018-20836)The Siemens     R3964 line discipline driver in drivers/tty/n_r3964.c     in the Linux kernel before 5.0.8 has multiple race     conditions.(CVE-2019-11486)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)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)A     n issue was discovered in the Linux kernel before     5.0.7. A NULL pointer dereference can occur when     megasas_create_frame_pool() fails in     megasas_alloc_cmds() in     drivers/scsi/megaraid/megaraid_sas_base.c. This causes     a Denial of Service, related to a     use-after-free.(CVE-2019-11810)An issue was discovered     in the Linux kernel before 5.0.4. There is a     use-after-free upon attempted read access to     /proc/ioports after the ipmi_si module is removed,     related to drivers/char/ipmi/ipmi_si_intf.c,     drivers/char/ipmi/ipmi_si_mem_io.c, and     drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)A     flaw was found in the Linux kernel's handle_rx()     function in the [vhost_net] driver. A malicious virtual     guest, under specific conditions, can trigger an     out-of-bounds write in a kmalloc-8 slab on a virtual     host which may lead to a kernel memory corruption and a     system panic. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out. Versions from     v4.16 and newer are vulnerable.(CVE-2018-16880)An issue     was discovered in rds_tcp_kill_sock in net/rds/tcp.c in     the Linux kernel before 5.0.8. There is a race     condition leading to a use-after-free, related to net     namespace cleanup.(CVE-2019-11815)A flaw was found in     the Linux kernel in the function     hid_debug_events_read() in drivers/hid/hid-debug.c file     which may enter an infinite loop with certain     parameters passed from a userspace. A local privileged     user ('root') can cause a system lock up and a denial     of service. Versions from v4.18 and newer are     vulnerable.(CVE-2019-3819)A flaw was found in the Linux     kernel's 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). Versions     3.10, 4.14 and 4.18 are vulnerable.(CVE-2019-3882)An     infinite loop issue was found in the vhost_net kernel     module in Linux Kernel up to and including v5.1-rc6,     while handling incoming packets in handle_rx(). It     could occur if one end sends packets faster than the     other end can process them. A guest user, maybe remote     one, could use this flaw to stall the vhost_net kernel     thread, resulting in a DoS scenario.(CVE-2019-3900)In     the Linux Kernel before versions 4.20.8 and 4.19.21 a     use-after-free error in the 'sctp_sendmsg()' function     (net/sctp/socket.c) when handling SCTP_SENDALL flag can     be exploited to corrupt memory.(CVE-2019-8956)A flaw     was found in the Linux kernel's implementation of ext4     extent management. The kernel doesn't correctly     initialize memory regions in the extent tree block     which may be exported to a local user to obtain     sensitive information by reading empty/uninitialized     data from the filesystem.(CVE-2019-11833)An issue was     discovered in drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference.(CVE-2019-12382)An issue was     discovered in the efi subsystem in the Linux kernel     through 5.1.5. phys_efi_set_virtual_address_map in     arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory     allocation failures. NOTE: This id is disputed as not     being an issue because ?All the code touched by the     referenced commit runs only at boot, before any user     processes are started. Therefore, there is no     possibility for an unprivileged user to control     it.(CVE-2019-12380)An issue was discovered in the Linux     kernel before 5.2.3. An out of bounds access exists in     the function hclge_tm_schd_mode_vnet_base_cfg in the     file drivers     et/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.(CVE-2019-     15925)An issue was discovered in     dlpar_parse_cc_property in     arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6. There is an unchecked kstrdup of     prop-i1/4zname, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash).(CVE-2019-12614)An issue was discovered in     net/ipv4/sysctl_net_ipv4.c in the Linux kernel before     5.0.11. There is a net/ipv4/tcp_input.c signed integer     overflow in tcp_ack_update_rtt() when userspace writes     a very large integer to     /proc/syset/ipv4/tcp_min_rtt_wlen, leading to a denial     of service or possibly unspecified other impact, aka     CID-19fad20d15a6.(CVE-2019-18805)A flaw was found in     the way PTRACE_TRACEME functionality was handled in the     Linux kernel. The kernel's implementation of ptrace can     inadvertently grant elevated permissions to an attacker     who can then abuse the relationship between the tracer     and the process being traced. This flaw could allow a     local, unprivileged user to increase their privileges     on the system or cause a denial of     service.(CVE-2019-13272)An issue was discovered in     ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux     kernel through 5.1.5. There is an unchecked kmalloc of     new_ra, which might allow an attacker to cause a denial     of service (NULL pointer dereference and system crash).
    NOTE: This has been disputed as not an     issue.(CVE-2019-12378)An issue was discovered in     ip_ra_control in net/ipv4/ip_sockglue.c in the Linux     kernel through 5.1.5. There is an unchecked kmalloc of     new_ra, which might allow an attacker to cause a denial     of service (NULL pointer dereference and system crash).
    NOTE: this is disputed because new_ra is never used if     it is NULL.(CVE-2019-12381)An issue was discovered in     sunxi_divs_clk_setup in drivers/clk/sunxi/clk-sunxi.c     in the Linux kernel through 5.1.5. There is an     unchecked kstrndup of derived_name, which might allow     an attacker to cause a denial of service (NULL pointer     dereference and system crash). NOTE: This id is     disputed as not being an issue because 'The memory     allocation that was not checked is part of a code that     only runs at boot time, before user processes are     started. Therefore, there is no possibility for an     unprivileged user to control it, and no denial of     service.'.(CVE-2019-12455)An issue was discovered in     the MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel     through 5.1.5. It allows local users to cause a denial     of service or possibly have unspecified other impact by     changing the value of ioc_number between two kernel     reads of that value, aka a ''double fetch''     vulnerability. NOTE: a third party reports that this is     unexploitable because the doubly fetched value is not     used.(CVE-2019-12456)An issue was discovered in     get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in     the Linux kernel through 5.1.6. There is an unchecked     kstrdup_const of node_info-i1/4zvdev_port.name, which     might allow an attacker to cause a denial of service     (NULL pointer dereference and system     crash).(CVE-2019-12615)In parse_hid_report_descriptor     in drivers/input/tablet/gtco.c in the Linux kernel     through 5.2.1, a malicious USB device can send an HID     report that triggers an out-of-bounds write during     generation of debugging messages.(CVE-2019-13631)A     vulnerability was found in the Linux kernelaEURtms floppy     disk driver implementation. A local attacker with     access to the floppy device could call set_geometry in     drivers/block/floppy.c, which does not validate the     sect and head fields, causing an integer overflow and     out-of-bounds read. This flaw may crash the system or     allow an attacker to gather information causing     subsequent successful     attacks.(CVE-2019-14283)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 5.2.6. There is a     use-after-free caused by a malicious USB device in the     drivers/media/v4l2-core/v4l2-dev.c driver because     drivers/media/radio/radio-raremono.c does not properly     allocate memory.(CVE-2019-15211)An issue was discovered     in the Linux kernel before 5.0.10. There is a     use-after-free in the sound subsystem because card     disconnection causes certain data structures to be     deleted too early. This is related to sound/core/init.c     and sound/core/info.c.(CVE-2019-15214)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 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 before 5.2.1. There is a use-after-free     caused by a malicious USB device in the     driverset/wireless/intersil/p54/p54usb.c     driver.(CVE-2019-15220)An issue was discovered in the     Linux kernel before 5.1.17. There is a NULL pointer     dereference caused by a malicious USB device in the     sound/usb/line6/pcm.c driver.(CVE-2019-15221)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)An     issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9.
    XFS partially wedges when a chgrp fails on account of     being out of disk quota. xfs_setattr_nonsize is failing     to unlock the ILOCK after the xfs_qm_vop_chown_reserve     call fails. This is primarily a local DoS attack     vector, but it might result as well in remote DoS if     the XFS filesystem is exported for instance via     NFS.(CVE-2019-15538)An issue was discovered in the     Linux kernel before 5.0.19. There is an out-of-bounds     array access in __xfrm_policy_unlink, which will cause     denial of service, because verify_newpolicy_info in     net/xfrm/xfrm_user.c mishandles directory     validation.(CVE-2019-15666)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)An issue was discovered in the     Linux kernel before 5.0.5. There is a use-after-free     issue when hci_uart_register_dev() fails in     hci_uart_set_proto() in     drivers/bluetooth/hci_ldisc.c.(CVE-2019-15917)An issue     was discovered in the Linux kernel before 5.0.10.
    SMB2_write in fs/cifs/smb2pdu.c has a     use-after-free.(CVE-2019-15919)An issue was discovered     in the Linux kernel before 5.0.10. SMB2_read in     fs/cifs/smb2pdu.c has a use-after-free. NOTE: this was     not fixed correctly in 5.0.10 see the 5.0.11 ChangeLog,     which documents a memory leak.(CVE-2019-15920)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)An issue was     discovered in can_can_gw_rcv in net/can/gw.c in the     Linux kernel through 4.19.13. The CAN frame     modification rules allow bitwise logical operations     that can be also applied to the can_dlc field. Because     of a missing check, the CAN drivers may write arbitrary     content beyond the data registers in the CAN     controller's I/O memory when processing can-gw     manipulated outgoing frames. This is related to     cgw_csum_xor_rel. An unprivileged user can trigger a     system crash (general protection     fault).(CVE-2019-3701)A flaw was found in the Linux     kernel's Marvell wifi chip driver. A heap overflow in     mwifiex_update_bss_desc_with_ie function in     marvell/mwifiex/scan.c allows remote attackers to cause     a denial of service(system crash) or execute arbitrary     code.(CVE-2019-3846)A new software page cache side     channel attack scenario was discovered in operating     systems that implement the very common 'page cache'     caching mechanism. A malicious user/process could use     'in memory' page-cache knowledge to infer access     timings to shared memory and gain knowledge which can     be used to reduce effectiveness of cryptographic     strength by monitoring algorithmic behavior, infer     access patterns of memory to determine code paths     taken, and exfiltrate data to a blinded attacker     through page-granularity access times as a     side-channel.(CVE-2019-5489)In the Android kernel in     the video driver there is a kernel pointer leak due to     a WARN_ON statement. This could lead to local     information disclosure with System execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2019-9455)A vulnerability was found     in the arch/x86/lib/insn-eval.c function in the Linux     kernel. An attacker could corrupt the memory due to a     flaw in use-after-free access to an LDT entry caused by     a race condition between modify_ldt() and a #BR     exception for an MPX bounds violation.(CVE-2019-13233)

  - CVE-2019-0154: An unprotected read access to i915     registers has been fixed that could have been abused to     facilitate a local denial-of-service attack.
    (bsc#1135966)

  - CVE-2019-0155: A privilege escalation vulnerability has     been fixed in the i915 module that allowed batch buffers     from user mode to gain super user privileges.
    (bsc#1135967)

  - CVE-2019-16231: drivers/net/fjes/fjes_main.c did not     check the alloc_workqueue return value, leading to a     NULL pointer dereference (bnc#1150466).

  - CVE-2019-18805: There was a net/ipv4/tcp_input.c signed     integer overflow in tcp_ack_update_rtt() when userspace     writes a very large integer to     /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial     of service or possibly unspecified other impact, aka     CID-19fad20d15a6 (bnc#1156187).

  - CVE-2019-17055: base_sock_create in     drivers/isdn/mISDN/socket.c in the AF_ISDN network     module did not enforce CAP_NET_RAW, which means that     unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21 (bnc#1152782).

  - CVE-2019-16995: A memory leak exits in     hsr_dev_finalize() in net/hsr/hsr_device.c, if     hsr_add_port fails to add a port, which may cause denial     of service, aka CID-6caabe7f197d (bnc#1152685).

  - 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: drivers/scsi/qla2xxx/qla_os.c did not     check the alloc_workqueue return value, leading to a     NULL pointer dereference (bnc#1150457).

  - 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.

The SUSE Linux Enterprise 15-SP1 Azure 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 More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 (bnc#1117665 1152505 1155812 1155817 1155945) 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 (bnc#1139073 1152497 1152505 1152506). CVE-2019-18805: There was a signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6 (bnc#1156187).

CVE-2019-17055: The AF_NFC network module did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bnc#1152782).

CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port failed to add a port, which may have caused denial of service (bsc#1152685).

CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference.
(bsc#1150457).

CVE-2019-10220: Added sanity checks on the pathnames passed to the user space. (bsc#1144903).

CVE-2019-17666: rtlwifi: Fix potential overflow in P2P code (bsc#1154372).

CVE-2019-16232: Fix a potential NULL pointer dereference in the Marwell libertas driver (bsc#1150465).

CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150452).

CVE-2019-17133: cfg80211 wireless extension did not reject a long SSID IE, leading to a Buffer Overflow (bsc#1153158).

CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bsc#1152788).

The update package also includes non-security fixes. See advisory for details.
