An update of the linux package has been released.

The version of kernel installed on the remote host is prior to 4.14.192-147.314. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1480 advisory.

    2024-06-19: CVE-2020-14356 was added to this advisory.

    The Serial Attached SCSI (SAS) implementation in the Linux kernel mishandles a mutex within libsas. This     allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.
    (CVE-2017-18232)

    The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel can cause a NULL     pointer dereference in xfs_bmapi_write function. An attacker could trick a legitimate user or a privileged     attacker could exploit this by mounting a crafted xfs filesystem image to cause a kernel panic and thus a     denial of service. (CVE-2018-10323)

    The Linux kernel was found vulnerable to a NULL pointer dereference in the drivers/net/phy/mdio-bcm-     unimac.c:unimac_mdio_probe() function caused by an unchecked return value from the platform_get_resource()     function. A successful flaw exploitation can cause a system panic and a denial of service. This flaw is     believed not to be an attacker triggerable as bad return value can be caused by hardware misconfiguration.
    (CVE-2018-8043)

    A flaw was found in the AMD Cryptographic Co-processor driver in the Linux kernel. An attacker, able to     send invalid SHA type commands, could cause the system to crash. The highest threat from this     vulnerability is to system availability. (CVE-2019-18808)

    A flaw was found in the Linux kernel. The CX23888 Integrated Consumer Infrared Controller probe code     handles resource cleanup low memory conditions. A local attacker able to induce low memory conditions     could use this flaw to crash the system. The highest threat from this vulnerability is to system     availability. (CVE-2019-19054)

    A memory leak flaw was found in the adis_update_scan_mode_burst() function in     drivers/iio/imu/adis_buffer.c in the Linux kernel. This flaw allows attackers to cause a denial of     service. (CVE-2019-19061)

    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)

    A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.
    (CVE-2019-19074)

    A flaw was found in the way Linux kernel's KVM hypervisor handled deferred TLB flush requests from guest.
    A race condition may occur between the guest issuing a deferred TLB flush request to KVM, and then KVM     handling and acknowledging it. This may result in invalid address translations from TLB being used to     access guest memory, leading to a potential information leakage issue. An attacker may use this flaw to     access guest memory locations that it should not have access to. (CVE-2019-3016)

    In the Android kernel in F2FS driver there is a possible out of bounds read due to a missing bounds check.
    This could lead to local information disclosure with system execution privileges needed. User interaction     is not needed for exploitation. (CVE-2019-9445)

    A flaw was found in the ZRAM kernel module, where a user with a local account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device.
    With this vulnerability, continually reading the device may consume a large amount of system memory and     cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making     the system inoperable. (CVE-2020-10781)

    A flaw was discovered in the XFS source in the Linux kernel. This flaw allows an attacker with the ability     to mount an XFS filesystem, to trigger a denial of service while attempting to sync a file located on an     XFS v5 image with crafted metadata. (CVE-2020-12655)

    A flaw null pointer dereference in the Linux kernel cgroupv2 subsystem in versions before 5.7.10 was found     in the way when reboot the system. A local user could use this flaw to crash the system or escalate their     privileges on the system. (CVE-2020-14356)

    In the Linux kernel 4.4 through 5.7.6, usbtest_disconnect in drivers/usb/misc/usbtest.c has a memory leak,     aka CID-28ebeb8db770. (CVE-2020-15393)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - An out-of-bounds memory access flaw was found in the     Linux kernel's system call auditing implementation. On     a system with existing audit rules defined, a local,     unprivileged user could use this flaw to leak kernel     memory to user space or, potentially, crash the     system.(CVE-2014-3917i1/4%0

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net     namespaces.(CVE-2017-17448i1/4%0

  - A race condition flaw was found between the chown and     execve system calls. When changing the owner of a     setuid user binary to root, the race condition could     momentarily make the binary setuid root. A local,     unprivileged user could potentially use this flaw to     escalate their privileges on the     system.(CVE-2015-3339i1/4%0

  - Keberos 5 tickets being decoded when using the RXRPC     keys incorrectly assumes the size of a field. This     could lead to the size-remaining variable wrapping and     the data pointer going over the end of the buffer. This     could possibly lead to memory corruption and possible     privilege escalation.(CVE-2017-7482i1/4%0

  - The nfs_can_extend_write function in fs/nfs/write.c in     the Linux kernel before 3.13.3 relies on a write     delegation to extend a write operation without a     certain up-to-date verification, which allows local     users to obtain sensitive information from kernel     memory in opportunistic circumstances by writing to a     file in an NFS filesystem and then reading the same     file.(CVE-2014-2038i1/4%0

  - KVM in the Linux kernel before 4.8.12, when I/O APIC is     enabled, does not properly restrict the VCPU index,     which allows guest OS users to gain host OS privileges     or cause a denial of service (out-of-bounds array     access and host OS crash) via a crafted interrupt     request, related to arch/x86/kvm/ioapic.c and     arch/x86/kvm/ioapic.h.(CVE-2016-9777i1/4%0

  - The instruction decoder in arch/x86/kvm/emulate.c in     the KVM subsystem in the Linux kernel before 3.18-rc2     lacks intended decoder-table flags for certain     RIP-relative instructions, which allows guest OS users     to cause a denial of service (NULL pointer dereference     and host OS crash) via a crafted     application.(CVE-2014-8480i1/4%0

  - arch/x86/kernel/entry_32.S in the Linux kernel through     3.15.1 on 32-bit x86 platforms, when syscall auditing     is enabled and the sep CPU feature flag is set, allows     local users to cause a denial of service (OOPS and     system crash) via an invalid syscall number, as     demonstrated by number 1000.(CVE-2014-4508i1/4%0

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly restrict the mount     namespace, which allows local users to gain privileges     by mounting an overlayfs filesystem on top of a FUSE     filesystem, and then executing a crafted setuid     program.(CVE-2016-1576i1/4%0

  - A use-after-free vulnerability was found when issuing     an ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption     or possibly privilege escalation.(CVE-2017-15265i1/4%0

  - The drivers/uwb/uwbd.c in the Linux kernel, before     4.13.6, allows local users to cause a denial of service     (general protection fault and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16526i1/4%0

  - The Linux kernel was found vulnerable to a NULL pointer     dereference in the     drivers/net/phy/mdio-bcm-unimac.c:unimac_mdio_probe()     function caused by an unchecked return value from the     platform_get_resource() function. A successful flaw     exploitation can cause a system panic and a denial of     service. This flaw is believed not to be an attacker     triggerable as bad return value can be caused by     hardware misconfiguration.(CVE-2018-8043i1/4%0

  - A flaw was found in the Linux kernel SCSI subsystem,     which allowed a local user to gain privileges or cause     a denial of service (memory corruption and system     crash) by issuing an SG_IO ioctl call while a device     was being detached.(CVE-2015-8962i1/4%0

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-7913i1/4%0

  - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver     in the Linux kernel through 4.0.5 does not ensure that     certain length values are sufficiently large, which     allows remote attackers to cause a denial of service     (system crash or large loop) or possibly execute     arbitrary code via a crafted packet, related to the (1)     oz_usb_rx and (2) oz_usb_handle_ep_data     functions.(CVE-2015-4002i1/4%0

  - Race condition in the environ_read() function in     'fs/proc/base.c' in the Linux kernel before 4.5.4     allows local users to obtain sensitive information from     kernel memory by reading a '/proc/*/environ' file     during a process-setup time interval in which     environment-variable copying is     incomplete.(CVE-2016-7916i1/4%0

  - Integer signedness error in the oz_hcd_get_desc_cnf     function in drivers/staging/ozwpan/ozhcd.c in the     OZWPAN driver in the Linux kernel through 4.0.5 allows     remote attackers to cause a denial of service (system     crash) or possibly execute arbitrary code via a crafted     packet.(CVE-2015-4001i1/4%0

  - A vulnerability was found in the Linux kernel when     peeling off an association to the socket in another     network namespace. All transports in this association     are not to be rehashed and keep using the old key in     hashtable, thus removing transports from hashtable when     closing the socket, all transports are being freed.
    Later on a use-after-free issue could be caused when     looking up an association and dereferencing the     transports.(CVE-2017-15115i1/4%0

  - The evm_verify_hmac function in     security/integrity/evm/evm_main.c in the Linux kernel     before 4.5 does not properly copy data, which makes it     easier for local users to forge MAC values via a timing     side-channel attack.(CVE-2016-2085i1/4%0

  - A flaw was discovered in processing setsockopt for 32     bit processes on 64 bit systems. This flaw will allow     attackers to alter arbitrary kernel memory when     unloading a kernel module. This action is usually     restricted to root-privileged users but can also be     leveraged if the kernel is compiled with CONFIG_USER_NS     and CONFIG_NET_NS and the user is granted elevated     privileges.(CVE-2016-4997i1/4%0

The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to 4.4.121 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-8781: The udl_fb_mmap function in     drivers/gpu/drm/udl/udl_fb.c had an integer-overflow     vulnerability that allowed local users with access to     the udldrmfb driver to obtain full read and write     permissions on kernel physical pages, resulting in a     code execution in kernel space (bnc#1090643).

  - CVE-2018-10124: The kill_something_info function in     kernel/signal.c might have allowed local users to cause     a denial of service via an INT_MIN argument     (bnc#1089752).

  - CVE-2018-10087: The kernel_wait4 function in     kernel/exit.c might have allowed local users to cause a     denial of service by triggering an attempted use of the
    -INT_MIN value (bnc#1089608).

  - CVE-2017-18257: The __get_data_block function in     fs/f2fs/data.c in the Linux kernel allowed local users     to cause a denial of service (integer overflow and loop)     via crafted use of the open and fallocate system calls     with an FS_IOC_FIEMAP ioctl. (bnc#1088241)

  - CVE-2018-8822: Incorrect buffer length handling in the     ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c     could be exploited by malicious NCPFS servers to crash     the kernel or execute code (bnc#1086162).

  - CVE-2018-8043: The unimac_mdio_probe function in     drivers/net/phy/mdio-bcm-unimac.c did not validate     certain resource availability, which allowed local users     to cause a denial of service (NULL pointer dereference)     (bnc#1084829).

  - CVE-2018-7740: The resv_map_release function in     mm/hugetlb.c allowed local users to cause a denial of     service (BUG) via a crafted application that made mmap     system calls and has a large pgoff argument to the     remap_file_pages system call (bnc#1084353).

  - CVE-2018-1087: And an unprivileged KVM guest user could     use this flaw to potentially escalate their privileges     inside a guest. (bsc#1087088)

  - CVE-2018-8897: An unprivileged system user could use     incorrect set up interrupt stacks to crash the Linux     kernel resulting in DoS issue. (bsc#1087088)

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