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).

New kernel packages are available for Slackware 14.2 to fix security issues.

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 :

  - A heap-based buffer overflow was discovered in the     Linux kernel's 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 allow the remote device to     cause a denial of service (system crash) or possibly     execute arbitrary code.(CVE-2019-14895)

  - A flaw was found in the fix for CVE-2019-11135, 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)

  - A flaw was found in the way Intel CPUs handle     speculative execution of instructions when the TSX     Asynchronous Abort (TAA) error occurs. A local     authenticated attacker with the ability to monitor     execution times could infer the TSX memory state by     comparing abort execution times. This could allow     information disclosure via this observed side-channel     for any TSX transaction being executed while an     attacker is able to observe abort timing. Intel's     Transactional Synchronisation Extensions (TSX) are set     of instructions which enable transactional memory     support to improve performance of the multi-threaded     applications, in the lock-protected critical sections.
    The CPU executes instructions in the critical-sections     as transactions, while ensuring their atomic state.
    When such transaction execution is unsuccessful, the     processor cannot ensure atomic updates to the     transaction memory, so the processor rolls back or     aborts such transaction execution. While TSX     Asynchronous Abort (TAA) is pending, CPU may continue     to read data from architectural buffers and pass it to     the dependent speculative operations. This may cause     information leakage via speculative side-channel means,     which is quite similar to the Microarchitectural Data     Sampling (MDS) issue.(CVE-2019-11135)

  - An out-of-bounds memory write issue was found in the     way the Linux kernel's KVM hypervisor handled the     'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID     features emulated by the KVM hypervisor. A user or     process able to access the '/dev/kvm' device could use     this flaw to crash the system, resulting in a denial of     service.(CVE-2019-19332)

  - A flaw was found in the Linux kernel's scheduler, where     it can allow attackers to cause a denial of service     against non-CPU-bound applications by generating a     workload that triggers unwanted scheduling slice     expiration. A local attacker who can trigger a specific     workload type could abuse this technique to trigger a     system to be seen as degraded, and possibly trigger     workload-rebalance in systems that use the     slice-expiration metric as a measure of system     health.(CVE-2019-19922)

  - A stack-based buffer overflow was found in the Linux     kernel's Marvell WiFi chip driver. An attacker is able     to cause a denial of service (system crash) or,     possibly execute arbitrary code, when a STA works in     IBSS mode (allows connecting stations together without     the use of an AP) and connects to another     STA.(CVE-2019-14897)

  - A heap-based buffer overflow vulnerability was found in     the Linux kernel's Marvell WiFi chip driver. A remote     attacker could cause a denial of service (system crash)     or, possibly execute arbitrary code, when the     lbs_ibss_join_existing function is called after a STA     connects to an AP.(CVE-2019-14896)

  - A flaw was found in the Linux kernel in versions     through 5.4.6, containing information leaks of     uninitialized memory to a USB device. The latest     findings show that the uninitialized memory allocation     was not leading to an information leak, but was     allocating the memory assigned with data on the next     line and hence causing no violation..(CVE-2019-19947)

  - A flaw was found in the Linux kernel's implementation     of the Datagram Congestion Control Protocol (DCCP). A     local attacker with access to the system can create     DCCP sockets to cause a memory leak and repeat this     operation to exhaust all memory and panic the     system.(CVE-2019-20096)

  - A flaw was found in the Linux kernel's mwifiex driver     implementation when connecting to other WiFi devices in     'Test Mode.' A kernel memory leak can occur if an error     condition is met during the parameter negotiation. This     issue can lead to a denial of service if multiple error     conditions meeting the repeated connection attempts are     attempted.(CVE-2019-20095)

  - A flaw was found in the Linux kernel's implementation     of the WiFi station handoff code. An attacker within     the radio range could use this flaw to deny a valid     device from joining the access point.(CVE-2019-5108)

  - 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)

  - fs/namei.c in the Linux kernel before 5.5 has a     may_create_in_sticky use-after-free, which allows local     users to cause a denial of service (OOPS) or possibly     obtain sensitive information from kernel memory, aka     CID-d0cb50185ae9. One attack vector may be an open     system call for a UNIX domain socket, if the socket is     being moved to a new parent directory and its old     parent directory is being removed.(CVE-2020-8428)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the n_tty_receive_buf_common     function in drivers/tty/n_tty.c.(CVE-2020-8648)

  - An issue was discovered in the Linux kernel through     5.5.6. set_fdc in drivers/block/floppy.c leads to a     wait_til_ready out-of-bounds read because the FDC index     is not checked for errors before assigning it, aka     CID-2e90ca68b0d2.(CVE-2020-9383)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the vgacon_invert_region     function in     drivers/video/console/vgacon.c.(CVE-2020-8649)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c.(CVE-2020-8647)

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.

The remote OracleVM system is missing necessary patches to address security updates:

  - A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before     4.18.0, 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 allow the remote device     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895)

  - ext4_empty_dir in fs/ext4/namei.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference     because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be zero. (CVE-2019-19037)

  - In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and     unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list     in fs/ext4/super.c. (CVE-2019-19447)

  - An issue was discovered in the Linux kernel before 5.2.6. On NUMA systems, the Linux fair scheduler has a     use-after-free in show_numa_stats() because NUMA fault statistics are inappropriately freed, aka     CID-16d51a590a8c. (CVE-2019-20934)

  - 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)

  - usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because     a transfer occurs without a reference, aka CID-056ad39ee925. (CVE-2020-12464)

  - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows     local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a     double fetch vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states The security impact of this     bug is not as bad as it could have been because these operations are all privileged and root already has     enormous destructive power. (CVE-2020-12652)

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)

  - Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain     privileges or cause a denial of service by leveraging improper access to a certain error field.
    (CVE-2020-15436)

  - A flaw was found in Linux Kernel because access to the global variable fg_console is not properly     synchronized leading to a use after free in con_font_op. (CVE-2020-25668)

  - A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw     allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that     relies on UDP source port randomization are indirectly affected as well on the Linux Based Products     (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4,     SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE     W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All     versions, SIMATIC NET CP 1243-1 (incl. SIPLUS variants): Versions 3.1.39 and later, SIMATIC NET CP 1243-7     LTE EU: Version (CVE-2020-25705)

  - A buffer over-read (at the framebuffer layer) in the fbcon code in the Linux kernel before 5.8.15 could be     used by local attackers to read kernel memory, aka CID-6735b4632def. (CVE-2020-28915)

  - A slab-out-of-bounds read in fbcon in the Linux kernel before 5.9.7 could be used by local attackers to     read privileged information or potentially crash the kernel, aka CID-3c4e0dff2095. This occurs because     KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height. (CVE-2020-28974)
