The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-14895: A heap-based buffer overflow was discovered in the Linux kernel in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could have allowed the remote device to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1157158).

CVE-2019-18660: The Linux kernel on powerpc allowed Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c (bnc#1157038).

CVE-2019-18683: An issue was discovered in drivers/media/platform/vivid in the Linux kernel. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded.
There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free (bnc#1155897).

CVE-2019-18809: A memory leak in the af9005_identify_state() function in drivers/media/usb/dvb-usb/af9005.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1156258).

CVE-2019-19062: A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures (bnc#1157333).

CVE-2019-19057: Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures (bnc#1157197).

CVE-2019-19056: A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures (bnc#1157197).

CVE-2019-19068: A memory leak in the rtl8xxxu_submit_int_urb() function in drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures (bnc#1157307).

CVE-2019-19063: Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1157298).

CVE-2019-19227: In the AppleTalk subsystem in the Linux kernel there was a potential NULL pointer dereference because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c and net/appletalk/ddp.c, as demonstrated by unregister_snap_client (bnc#1157678).

CVE-2019-19065: A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering rhashtable_init() failures (bnc#1157191).

CVE-2019-19077: A memory leak in the bnxt_re_create_srq() function in drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering copy to udata failures (bnc#1157171).

CVE-2019-19052: A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures (bnc#1157324).

CVE-2019-19067: Four memory leaks in the acp_hw_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering mfd_add_hotplug_devices() or pm_genpd_add_device() failures (bsc#1157180).

CVE-2019-19060: A memory leak in the adis_update_scan_mode() function in drivers/iio/imu/adis_buffer.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1157178).

CVE-2019-19049: A memory leak in the unittest_data_add() function in drivers/of/unittest.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering of_fdt_unflatten_tree() failures (bsc#1157173).

CVE-2019-19075: A memory leak in the ca8210_probe() function in drivers/net/ieee802154/ca8210.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering ca8210_get_platform_data() failures (bnc#1157162).

CVE-2019-19058: A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering alloc_page() failures (bnc#1157145).

CVE-2019-19074: A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1157143).

CVE-2019-19073: Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel allowed 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 (bnc#1157070).

CVE-2019-15916: An issue was discovered in the Linux kernel There was a memory leak in register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service (bnc#1149448).

CVE-2019-16231: drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 did not check the alloc_workqueue return value, leading to a NULL pointer dereference (bnc#1150466).

CVE-2019-18805: An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel 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 (bnc#1156187).

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

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

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

CVE-2019-19529: There was a use-after-free bug that can be caused by a malicious USB device in the drivers/net/can/usb/mcba_usb.c driver (bnc#1158381).

CVE-2019-14901: A heap overflow flaw was found in the Linux kernel in Marvell WiFi chip driver. The vulnerability allowed a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system (bnc#1157042).

CVE-2019-14895: A heap-based buffer overflow was discovered in the Linux kernel in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could have allowed the remote device to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1157158).

CVE-2019-18660: The Linux kernel on powerpc allowed Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c (bnc#1157038).

CVE-2019-18683: An issue was discovered in drivers/media/platform/vivid in the Linux kernel. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded.
There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free (bnc#1155897).

The version of AOS installed on the remote host is prior to 5.17.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.17.1 advisory.

  - When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to     Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP     connection. If such connections are available to an attacker, they can be exploited in ways that may be     surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped     with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected     (and recommended in the security guide) that this Connector would be disabled if not required. This     vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the     web application - processing any file in the web application as a JSP Further, if the web application     allowed file upload and stored those files within the web application (or the attacker was able to control     the content of the web application by some other means) then this, along with the ability to process a     file as a JSP, made remote code execution possible. It is important to note that mitigation is only     required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth     approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to     Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP     Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading     to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.
    (CVE-2020-1938)

  - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a     certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)

  - 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)

  - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where,     the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by     the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
    (CVE-2019-19338)

  - The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which     allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.
    (CVE-2015-8035)
