The version of AOS installed on the remote host is prior to 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

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

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

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:

This will cause a BUG and denial of     service.(CVE-2019-15807)A vulnerability was found in     Linux kernel's, versions up to 3.10, implementation of     overlayfs. An attacker with local access can create a     denial of service situation via NULL pointer     dereference in ovl_posix_acl_create function in     fs/overlayfs/dir.c. This can allow attackers with     ability to create directories on overlayfs to crash the     kernel creating a denial of service     (DOS).(CVE-2019-10140)In the Linux kernel, a certain     net/ipv4/tcp_output.c change, which was properly     incorporated into 4.16.12, was incorrectly backported     to the earlier longterm kernels, introducing a new     vulnerability that was potentially more severe than the     issue that was intended to be fixed by backporting.
    Specifically, by adding to a write queue between     disconnection and re-connection, a local attacker can     trigger multiple use-after-free conditions. This can     result in a kernel crash, or potentially in privilege     escalation.(CVE-2019-15239)check_input_term in     sound/usb/mixer.c in the Linux kernel through 5.2.9     mishandles recursion, leading to kernel stack     exhaustion.(CVE-2019-15118)drivers     et/wireless/ath/ath10k/usb.c in the Linux kernel     through 5.2.8 has a NULL pointer dereference via an     incomplete address in an endpoint     descriptor.(CVE-2019-15099)drivers     et/wireless/ath/ath6kl/usb.c in the Linux kernel     through 5.2.9 has a NULL pointer dereference via an     incomplete address in an endpoint     descriptor.(CVE-2019-15098)A flaw was found in the     Linux kernel's Bluetooth implementation of UART.

An attacker can use this flaw to     crash the system, corrupt memory, or create other     adverse security     affects.(CVE-2019-10142)drivers/media/usb/dvb-usb/techn     isat-usb2.c in the Linux kernel through 5.2.9 has an     out-of-bounds read via crafted USB device traffic     (which may be remote via usbip or     usbredir).(CVE-2019-15505)An issue was discovered in     the Linux kernel before 5.0.4. The 9p filesystem did     not protect i_size_write() properly, which causes an     i_size_read() infinite loop and denial of service on     SMP systems.(CVE-2019-16413)An issue was discovered in     xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux     kernel through 5.2.9. XFS partially wedges when a chgrp     fails on account of being out of disk quota.
    xfs_setattr_nonsize is failing to unlock the ILOCK     after the xfs_qm_vop_chown_reserve call fails. This is     primarily a local DoS attack vector, but it might     result as well in remote DoS if the XFS filesystem is     exported for instance via NFS.(CVE-2019-15538)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)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)An     information disclosure vulnerability exists when     certain central processing units (CPU) speculatively     access memory, aka 'Windows Kernel Information     Disclosure Vulnerability'.
    (CVE-2019-1125)drivers/scsi/qla2xxx/qla_os.c in the     Linux kernel 5.2.14 does not check the alloc_workqueue     return value, leading to a NULL pointer     dereference.(CVE-2019-16233)An issue was discovered in     the Linux kernel before 5.0.11. fm10k_init_module in     drivers et/ethernet/intel/fm10k/fm10k_main.c has a NULL     pointer dereference because there is no -ENOMEM upon an     alloc_workqueue failure.(CVE-2019-15924)An issue was     discovered in the Linux kernel before 5.2.1.

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4184-1 advisory.

    Stephan van Schaik, Alyssa Milburn, Sebastian sterlund, Pietro Frigo, Kaveh Razavi, Herbert Bos,     Cristiano Giuffrida, Giorgi Maisuradze, Moritz Lipp, Michael Schwarz, Daniel Gruss, and Jo Van Bulck     discovered that Intel processors using Transactional Synchronization Extensions (TSX) could expose memory     contents previously stored in microarchitectural buffers to a malicious process that is executing on the     same CPU core. A local attacker could use this to expose sensitive information. (CVE-2019-11135)

    It was discovered that the Intel i915 graphics chipsets allowed userspace to modify page table entries via     writes to MMIO from the Blitter Command Streamer and expose kernel memory information. A local attacker     could use this to expose sensitive information or possibly elevate privileges. (CVE-2019-0155)

    Deepak Gupta discovered that on certain Intel processors, the Linux kernel did not properly perform     invalidation on page table updates by virtual guest operating systems. A local attacker in a guest VM     could use this to cause a denial of service (host system crash). (CVE-2018-12207)

    It was discovered that the Intel i915 graphics chipsets could cause a system hang when userspace performed     a read from GT memory mapped input output (MMIO) when the product is in certain low power states. A local     attacker could use this to cause a denial of service. (CVE-2019-0154)

    Hui Peng discovered that the Atheros AR6004 USB Wi-Fi device driver for the Linux kernel did not properly     validate endpoint descriptors returned by the device. A physically proximate attacker could use this to     cause a denial of service (system crash). (CVE-2019-15098)

    Jann Horn discovered a reference count underflow in the shiftfs implementation in the Linux kernel. A     local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2019-15791)

    Jann Horn discovered a type confusion vulnerability in the shiftfs implementation in the Linux kernel. A     local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2019-15792)

    Jann Horn discovered that the shiftfs implementation in the Linux kernel did not use the correct file     system uid/gid when the user namespace of a lower file system is not in the init user namespace. A local     attacker could use this to possibly bypass DAC permissions or have some other unspecified impact.
    (CVE-2019-15793)

    Ori Nimron discovered that the AX25 network protocol implementation in the Linux kernel did not properly     perform permissions checks. A local attacker could use this to create a raw socket. (CVE-2019-17052)

    Ori Nimron discovered that the IEEE 802.15.4 Low-Rate Wireless network protocol implementation in the     Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw     socket. (CVE-2019-17053)

    Ori Nimron discovered that the Appletalk network protocol implementation in the Linux kernel did not     properly perform permissions checks. A local attacker could use this to create a raw socket.
    (CVE-2019-17054)

    Ori Nimron discovered that the modular ISDN network protocol implementation in the Linux kernel did not     properly perform permissions checks. A local attacker could use this to create a raw socket.
    (CVE-2019-17055)

    Ori Nimron discovered that the Near field Communication (NFC) network protocol implementation in the Linux     kernel did not properly perform permissions checks. A local attacker could use this to create a raw     socket. (CVE-2019-17056)

    Nico Waisman discovered that a buffer overflow existed in the Realtek Wi-Fi driver for the Linux kernel     when handling Notice of Absence frames. A physically proximate attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2019-17666)
