Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1016 advisory.

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - The KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to     the current task's default request-key keyring via the request_key() system call, allowing a local user     to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write     permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.
    (CVE-2017-17807)

  - The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num     from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds     (OOB) read that potentially allows arbitrary read in the kernel address space. (CVE-2018-19985)

  - An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during     the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.
    (CVE-2018-20169)

  - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows 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. (CVE-2018-7191)

  - 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)

  - The Linux kernel before 4.8 allows 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. (CVE-2019-11190)

  - 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 drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL     pointer dereference (CVE-2019-12382)

  - 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 through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled,     a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn()     system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and     arch/powerpc/kernel/signal_64.c. (CVE-2019-13648)

  - 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)

  - There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell     wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or     possibly execute arbitrary code. (CVE-2019-14814)

  - A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params()     function of Marvell Wifi Driver. (CVE-2019-14815)

  - 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 5.0.10. 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 5.1.17. 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 5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check     the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)

  - The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is     not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to     arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. (CVE-2019-18660)

  - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.
    As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it     is possible for the specified target task to perform an execve() syscall with setuid execution before     perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check     and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged     execve() calls. This issue affects kernel versions before 4.8. (CVE-2019-3901)

  - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An     attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations     before the required authentication process has completed. This could lead to different denial-of-service     scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already     existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge     Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. 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-2019-9503)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003577 advisory.

    There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell     wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or     possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

The Linux Kernel KVM hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 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 CVE-2019-16233:

CVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific socket option, an attacker could control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)

CVE-2019-9506: The Bluetooth BR/EDR specification used to permit sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and inject arbitrary ciphertext without the victim noticing (bnc#1137865).

CVE-2019-10220

Various developers and researchers found that if a crafted file- system or malicious file server presented a directory with filenames including a '/' character, this could confuse and possibly defeat security checks in applications that read the directory.

The kernel will now return an error when reading such a directory, rather than passing the invalid filenames on to user-space.

CVE-2019-14615

It was discovered that Intel 9th and 10th generation GPUs did not clear user-visible state during a context switch, which resulted in information leaks between GPU tasks. This has been mitigated in the i915 driver.

The syzkaller tool discovered a use-after-free bug in the atusb driver for IEEE 802.15.4 networking. An attacker able to add and remove USB devices could possibly use this to cause a denial of service (memory corruption or crash) or for privilege escalation.

CVE-2019-19527

The syzkaller tool discovered that the hiddev driver did not correctly handle races between a task opening the device and disconnection of the underlying hardware. A local user permitted to access hiddev devices, and able to add and remove USB devices, could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-19530

The syzkaller tool discovered a potential use-after-free in the cdc-acm network driver. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-19531

The syzkaller tool discovered a use-after-free bug in the yurex USB driver. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-19532

The syzkaller tool discovered a potential heap buffer overflow in the hid-gaff input driver, which was also found to exist in many other input drivers. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-19533

The syzkaller tool discovered that the ttusb-dec media driver was missing initialisation of a structure, which could leak sensitive information from kernel memory.

CVE-2019-19534, CVE-2019-19535, CVE-2019-19536

The syzkaller tool discovered that the peak_usb CAN driver was missing initialisation of some structures, which could leak sensitive information from kernel memory.

CVE-2019-19537

The syzkaller tool discovered race conditions in the USB stack, involving character device registration. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-19767

The syzkaller tool discovered that crafted ext4 volumes could trigger a buffer overflow in the ext4 filesystem driver. An attacker able to mount such a volume could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-19947

It was discovered that the kvaser_usb CAN driver was missing initialisation of some structures, which could leak sensitive information from kernel memory.

CVE-2019-19965

Gao Chuan reported a race condition in the libsas library used by SCSI host drivers, which could lead to a NULL pointer dereference. An attacker able to add and remove SCSI devices could use this to cause a denial of service (BUG/oops).

CVE-2019-20096

The Hulk Robot tool discovered a potential memory leak in the DCCP protocol implementation. This may be exploitable by local users, or by remote attackers if the system uses DCCP, to cause a denial of service (out of memory).

For Debian 8 'Jessie', these problems have been fixed in version 4.9.210-1~deb8u1. This update additionally fixes Debian bugs #869511 and 945023; and includes many more bug fixes from stable updates 4.9.190-4.9.210 inclusive.
