    __blk_drain_queue() use-after-free because a certain error case is mishandled. (CVE-2018-20856)

  - Bluetooth firmware or operating system software drivers in macOS versions before 10.13, High Sierra and     iOS versions before 11.4, and Android versions before the 2018-06-05 patch may not sufficiently validate     elliptic curve parameters used to generate public keys during a Diffie-Hellman key exchange, which may     allow a remote attacker to obtain the encryption key used by the device. (CVE-2018-5383)

  - A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other     consequences. (CVE-2019-10126)

  - An information disclosure vulnerability exists when certain central processing units (CPU) speculatively     access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from     CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)

  - 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->name, 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 the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in     net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL     pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in     net/nfc/llcp_core.c. (CVE-2019-12818)

  - An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in     drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free.
    This will cause a denial of service. (CVE-2019-12819)

  - A NULL pointer dereference vulnerability in the function nfc_genl_deactivate_target() in net/nfc/netlink.c     in the Linux kernel before 5.1.13 can be triggered by a malicious user-mode program that omits certain NFC     attributes, leading to denial of service. (CVE-2019-12984)

  - In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an     LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds     violation. (CVE-2019-13233)

  - In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the     credentials of a process that wants to create a ptrace relationship, which allows local users to obtain     root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops     privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an     object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of     a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper     with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.
    (CVE-2019-13272)

  - Bluetooth firmware or operating system software drivers in macOS versions before 10.13, High Sierra and     iOS versions before 11.4, and Android versions before the 2018-06-05 patch may not sufficiently validate     elliptic curve parameters used to generate public keys during a Diffie-Hellman key exchange, which may     allow a remote attacker to obtain the encryption key used by the device. (CVE-2018-5383)

  - Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may     allow an unauthenticated user to potentially enable denial of service via adjacent access. (CVE-2019-0136)

  - A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other     consequences. (CVE-2019-10126)

  - A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before     4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware     could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.
    (CVE-2019-10207)

  - In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel     produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page     that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)

  - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel     address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel     image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and     ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This     key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via     enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the     attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled     IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic     is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the     attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP     addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to     have a dependency on an address associated with a network namespace. (CVE-2019-10639)

  - Insufficient input validation in Kernel Mode Driver in Intel(R) i915 Graphics for Linux before version 5.0     may allow an authenticated user to potentially enable escalation of privilege via local access.
    (CVE-2019-11085)

  - 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)

  - An 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 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)

  - fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the     extent tree block, which might allow local users to obtain sensitive information by reading uninitialized     data in the filesystem. (CVE-2019-11833)

  - The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a     local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command,     because a name field may not end with a '\0' character. (CVE-2019-11884)

  - An issue was discovered in the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in     net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL     pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in     net/nfc/llcp_core.c. (CVE-2019-12818)

  - An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in     drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free.
    This will cause a denial of service. (CVE-2019-12819)

  - A NULL pointer dereference vulnerability in the function nfc_genl_deactivate_target() in net/nfc/netlink.c     in the Linux kernel before 5.1.13 can be triggered by a malicious user-mode program that omits certain NFC     attributes, leading to denial of service. (CVE-2019-12984)

  - In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an     LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds     violation. (CVE-2019-13233)

  - In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the     credentials of a process that wants to create a ptrace relationship, which allows local users to obtain     root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops     privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an     object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of     a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper     with PTRACE_TRACEME.

  - In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by     default. (CVE-2019-14283)

  - In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setup_format_params     division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry     with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should     be called. It can be triggered by an unprivileged local user even when a floppy disk has not been     inserted. NOTE: QEMU creates the floppy device by default. (CVE-2019-14284)

  - In the Linux kernel before 4.16.4, a double-locking error in drivers/usb/dwc3/gadget.c may potentially     cause a deadlock with f_hid. (CVE-2019-14763)

  - An issue was discovered in drivers/scsi/qedi/qedi_dbg.c in the Linux kernel before 5.1.12. In the     qedi_dbg_* family of functions, there is an out-of-bounds read. (CVE-2019-15090)

  - 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 5.1.8. 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 5.0.10. 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 5.2.6. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/cpia2/cpia2_usb.c driver. (CVE-2019-15215)

  - 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 5.1.8. 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 5.2.1. There is a use-after-free caused by a malicious     USB device in the drivers/net/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)

  - In em28xx_unregister_dvb of em28xx-dvb.c, there is a possible use after free issue. This could lead to     local escalation of privilege with no additional execution privileges needed. User interaction is not     needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-111761954References:
    Upstream kernel (CVE-2019-2024)

  - In uvc_parse_standard_control of uvc_driver.c, there is a possible out-of-bound read due to improper input     validation. This could lead to local information disclosure with no additional execution privileges     needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel.
    Android ID: A-111760968. (CVE-2019-2101)

  - 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.
    The privileged user root with CAP_NET_ADMIN can create a CAN frame modification rule that makes the data     length code a higher value than the available CAN frame data size. In combination with a configured     checksum calculation where the result is stored relatively to the end of the data (e.g. cgw_csum_xor_rel)     the tail of the skb (e.g. frag_list pointer in skb_shared_info) can be rewritten which finally can cause a     system crash. 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.
    (CVE-2019-3701)

  - 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 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)

  - 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)

  - The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from influencing the key length negotiation. This allows practical     brute-force attacks (aka KNOB) that can decrypt traffic and inject arbitrary ciphertext without the     victim noticing. (CVE-2019-9506)

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

The version of AOS installed on the remote host is prior to 5.16.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.16.0.1 advisory.

  - OpenSLP as used in ESXi and the Horizon DaaS appliances has a heap overwrite issue. VMware has evaluated     the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.
    (CVE-2019-5544)

  - Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly     sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox     < 68, and Thunderbird < 60.8. (CVE-2019-11729)

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

  - 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. A heap based buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other     consequences. (CVE-2019-10126)

  - 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 Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from influencing the key length negotiation. This allows practical     brute-force attacks (aka KNOB) that can decrypt traffic and inject arbitrary ciphertext without the     victim noticing. (CVE-2019-9506)

  - An information disclosure vulnerability exists when certain central processing units (CPU) speculatively     access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from     CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)

  - 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)

  - 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)

  - Insufficient access control in subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th     Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold     Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900     Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100 Processor Families may allow an     authenticated user to potentially enable denial of service via local access. (CVE-2019-0154)

  - 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)

  - 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)

  - Insufficient access control in a subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th     Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold     Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900     Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and E-2200 Processor Families; Intel(R)     Graphics Driver for Windows before 26.20.100.6813 (DCH) or 26.20.100.6812 and before 21.20.x.5077     (aka15.45.5077), i915 Linux Driver for Intel(R) Processor Graphics before versions 5.4-rc7, 5.3.11,     4.19.84, 4.14.154, 4.9.201, 4.4.201 may allow an authenticated user to potentially enable escalation of     privilege via local access. (CVE-2019-0155)

  - A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as     sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged     instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges     inside guest. (CVE-2018-10853)

  - The alarm_timer_nsleep function in kernel/time/alarmtimer.c in the Linux kernel through 4.17.3 has an     integer overflow via a large relative timeout because ktime_add_safe is not used. (CVE-2018-13053)

  - An issue was discovered in fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3. There is a NULL pointer     dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted     xfs image. This occurs because of a lack of proper validation that cached inodes are free during     allocation. (CVE-2018-13093)

  - An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may     occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp. (CVE-2018-13094)

  - An issue was discovered in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.17.3. A denial of     service (memory corruption and BUG) can occur for a corrupted xfs image upon encountering an inode that is     in extent format, but has more extents than fit in the inode fork. (CVE-2018-13095)

  - A flaw was found in the Linux Kernel where an attacker may be able to have an uncontrolled read to kernel-     memory from within a vm guest. A race condition between connect() and close() function may allow an     attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt     AF_VSOCK messages destined to other clients. (CVE-2018-14625)

  - drivers/infiniband/core/ucma.c in the Linux kernel through 4.17.11 allows ucma_leave_multicast to access a     certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial     of service (use-after-free). (CVE-2018-14734)

  - arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which     makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests. (CVE-2018-15594)

  - An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status     in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from     unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940. (CVE-2018-16658)

  - A flaw was found in the Linux kernel that allows the userspace to call memcpy_fromiovecend() and similar     functions with a zero offset and buffer length which causes the read beyond the buffer boundaries, in     certain cases causing a memory access fault and a system halt by accessing invalid memory address. This     issue only affects kernel version 3.10.x as shipped with Red Hat Enterprise Linux 7. (CVE-2018-16885)

  - Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks.
    If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of     mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it     has been released back to the page allocator and reused. This is fixed in the following kernel versions:
    4.9.135, 4.14.78, 4.18.16, 4.19. (CVE-2018-18281)

  - An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel     through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM     ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the     location of kernel code and data and bypass kernel security protections such as KASLR. (CVE-2018-7755)

  - Memory leak in the hwsim_new_radio_nl function in drivers/net/wireless/mac80211_hwsim.c in the Linux     kernel through 4.15.9 allows local users to cause a denial of service (memory consumption) by triggering     an out-of-array error case. (CVE-2018-8087)

  - In the hidp_process_report in bluetooth, there is an integer overflow. This could lead to an out of bounds     write with no additional execution privileges needed. User interaction is not needed for exploitation.
    Product: Android Versions: Android kernel Android ID: A-65853588 References: Upstream kernel.
    (CVE-2018-9363)

  - In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds 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. Product: Android Versions: Android kernel Android     ID: A-71361580. (CVE-2018-9516)

  - In pppol2tp_connect, there is possible memory corruption due to a use after free. 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-38159931. (CVE-2018-9517)

  - 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)

  - An 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)

  - fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the     extent tree block, which might allow local users to obtain sensitive information by reading uninitialized     data in the filesystem. (CVE-2019-11833)

  - A heap address information leak while using L2CAP_GET_CONF_OPT was discovered in the Linux kernel before     5.1-rc1. (CVE-2019-3459)

  - A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found in the Linux kernel     before 5.1-rc1. (CVE-2019-3460)

  - 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)

  - The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers     to observe page cache access patterns of other processes on the same system, potentially allowing sniffing     of secret information. (Fixing this affects the output of the fincore program.) Limited remote     exploitation may be possible, as demonstrated by latency differences in accessing public files from an     Apache HTTP Server. (CVE-2019-5489)

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

  - A buffer overflow in the fribidi_get_par_embedding_levels_ex() function in lib/fribidi-bidi.c of GNU     FriBidi through 1.0.7 allows an attacker to cause a denial of service or possibly execute arbitrary code     by delivering crafted text content to a user, when this content is then rendered by an application that     uses FriBidi for text layout calculations. Examples include any GNOME or GTK+ based application that uses     Pango for text layout, as this internally uses FriBidi for bidirectional text layout. For example, the     attacker can construct a crafted text file to be opened in GEdit, or a crafted IRC message to be viewed in     HexChat. (CVE-2019-18397)

  - 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)

  - In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12,     was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was     potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by     adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple     use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation.
    NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or     4.14.x longterm kernels before 4.14.139. (CVE-2019-15239)

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

The openSUSE Leap 15.1 was updated to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2019-11477: A sequence of SACKs may have been     crafted by a remote attacker such that one can trigger     an integer overflow, leading to a kernel panic.
    (bsc#1137586).

  - CVE-2019-11478: It was possible to send a crafted     sequence of SACKs which would fragment the TCP     retransmission queue. A remote attacker may have been     able to further exploit the fragmented queue to cause an     expensive linked-list walk for subsequent SACKs received     for that same TCP connection. (bsc#1137586)

  - CVE-2019-11479: It was possible to send a crafted     sequence of SACKs which would fragment the RACK send     map. A remote attacker may be able to further exploit     the fragmented send map to cause an expensive     linked-list walk for subsequent SACKs received for that     same TCP connection. This would have resulted in excess     resource consumption due to low mss values.
    (bsc#1137586)

  - CVE-2019-12819: The function __mdiobus_register() in     drivers/net/phy/mdio_bus.c calls put_device(), which     will trigger a fixed_mdio_bus_init use-after-free. This     will cause a denial of service (bnc#1138291).

  - CVE-2019-12818: The nfc_llcp_build_tlv function in     net/nfc/llcp_commands.c may return NULL. If the caller     did not check for this, it will trigger a NULL pointer     dereference. This will cause denial of service. This     affects nfc_llcp_build_gb in net/nfc/llcp_core.c     (bnc#1138293).

  - CVE-2019-12456: An issue was discovered in the     MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c that allowed 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. (bnc#1136922)

  - CVE-2019-12380: An issue was discovered in the efi     subsystem in the Linux kernel     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 (bnc#1136598).

  - CVE-2019-3846: 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 (bnc#1136424).

  - CVE-2019-10124: An attacker could exploit an issue in     the hwpoison implementation to cause a denial of service     (BUG). (bsc#1130699)

  - CVE-2019-12382: In the drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c was an unchecked kstrdup     of fwstr, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash) (bnc#1136586).

  - CVE-2019-11487: The Linux kernel allowed 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 (bnc#1133190).

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - Microarchitectural Store Buffer Data Sampling (MSBDS):
    Store buffers on some microprocessors utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. A list of impacted products     can be found here: https://www.intel.com/content/dam/www     /public/us/en/documents/corporate-     information/SA00233-microcode-update-     guidance_05132019.pdf (CVE-2018-12126)

  - Microarchitectural Load Port Data Sampling (MLPDS): Load     ports on some microprocessors utilizing speculative     execution may allow an authenticated user to potentially     enable information disclosure via a side channel with     local access. A list of impacted products can be found     here: https://www.intel.com/content/dam/www/public/us/en     /documents/corporate-information/SA00233-microcode-     update-guidance_05132019.pdf (CVE-2018-12127)

  - Microarchitectural Fill Buffer Data Sampling (MFBDS):
    Fill buffers on some microprocessors utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. A list of impacted products     can be found here: https://www.intel.com/content/dam/www     /public/us/en/documents/corporate-     information/SA00233-microcode-update-     guidance_05132019.pdf (CVE-2018-12130)

  - 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. A heap based     buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead     to memory corruption and possibly other consequences.
    (CVE-2019-10126)

  - A vulnerability was found in Linux kernel's, versions up     to 3.10, implementation of overlayfs. An attacker with     local access can create a denial of service situation     via NULL pointer dereference in ovl_posix_acl_create     function in fs/overlayfs/dir.c. This can allow attackers     with ability to create directories on overlayfs to crash     the kernel creating a denial of service (DOS).
    (CVE-2019-10140)

  - Microarchitectural Data Sampling Uncacheable Memory     (MDSUM): Uncacheable memory on some microprocessors     utilizing speculative execution may allow an     authenticated user to potentially enable information     disclosure via a side channel with local access. A list     of impacted products can be found here: https://www.inte     l.com/content/dam/www/public/us/en/documents/corporate-     information/SA00233-microcode-update-     guidance_05132019.pdf (CVE-2019-11091)

  - 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 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 Bluetooth BR/EDR specification up to and including     version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from influencing     the key length negotiation. This allows practical brute-     force attacks (aka KNOB) that can decrypt traffic and     inject arbitrary ciphertext without the victim noticing.
    (CVE-2019-9506)
