The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-11477: A sequence of SACKs may have been crafted 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 will fragment the TCP retransmission queue. An 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.

CVE-2019-11479: It was possible to send a crafted sequence of SACKs which will 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.

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-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel There 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-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel 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. (bnc#1120843).

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did 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. (bnc#1135281)

CVE-2018-7191: In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice.
This allowed 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.
(bnc#1135603)

CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat. (bnc#1131543)

CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bnc#1134537)

CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed 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. (bnc#1134848)

CVE-2018-17972: An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel It did not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. (bnc#1110785)

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel has multiple race conditions. (bnc#1133188)

The following new features were implemented: Updated the Chelsio cxgb4vf driver with the latest upstream patches. (fate#321660)

CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An 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.

CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data.
Further, it would consume additional resources such as CPU and NIC processing power.

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-2019-11487: The Linux kernel allowed page reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM existed. It could have occured with FUSE requests. (bnc#1133190)

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might have allowed local users to obtain sensitive information by reading uninitialized data in the filesystem. (bnc#1135281)

CVE-2018-7191: In the tun subsystem in the Linux kernel, dev_get_valid_name was not called before register_netdevice. This allowed 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. (bnc#1135603)

CVE-2019-11085: Insufficient input validation in Kernel Mode Driver in i915 Graphics for Linux may have allowed an authenticated user to potentially enable escalation of privilege via local access.
(bnc#1135278)

CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bnc#1134537)

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has kernel packages installed that are affected by multiple vulnerabilities:

  - 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)

  - 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)

  - 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 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 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)

  - 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)

  - 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 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)

  - 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 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)

  - 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)

  - 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)

  - 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)

  - 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 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)

  - 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 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 this issue but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 12 kernel version 3.12.61 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.

CVE-2019-11479: It was possible to send a crafted sequence of SACKs which would fragment the RACK send map. A remote attacker may have been 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.

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-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel 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 have been possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bnc#1120843)

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might have allowed local users to obtain sensitive information by reading uninitialized data in the filesystem. (bnc#1135281)

CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat. (bnc#1131543)

CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed 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. (bnc#1134848)

CVE-2018-17972: An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel It did not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. (bnc#1110785)

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

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