The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3871-5 advisory.

    Wen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the     Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10876,     CVE-2018-10879)

    Wen Xu discovered that a buffer overflow existed in the ext4 filesystem implementation in the Linux     kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10877)

    Wen Xu discovered that an out-of-bounds write vulnerability existed in the ext4 filesystem implementation     in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted,     could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10878,     CVE-2018-10882)

    Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly ensure that     xattr information remained in inode bodies. An attacker could use this to construct a malicious ext4 image     that, when mounted, could cause a denial of service (system crash). (CVE-2018-10880)

    Wen Xu discovered that the ext4 file system implementation in the Linux kernel could possibly perform an     out of bounds write when updating the journal for an inline file. An attacker could use this to construct     a malicious ext4 image that, when mounted, could cause a denial of service (system crash).
    (CVE-2018-10883)

    It was discovered that a race condition existed in the vsock address family implementation of the Linux     kernel that could lead to a use-after-free condition. A local attacker in a guest virtual machine could     use this to expose sensitive information (host machine kernel memory). (CVE-2018-14625)

    Cfir Cohen discovered that a use-after-free vulnerability existed in the KVM implementation of the Linux     kernel, when handling interrupts in environments where nested virtualization is in use (nested KVM     virtualization is not enabled by default in Ubuntu kernels). A local attacker in a guest VM could possibly     use this to gain administrative privileges in a host machine. (CVE-2018-16882)

    Jann Horn discovered that the procfs file system implementation in the Linux kernel did not properly     restrict the ability to inspect the kernel stack of an arbitrary task. A local attacker could use this to     expose sensitive information. (CVE-2018-17972)

    Jann Horn discovered that the mremap() system call in the Linux kernel did not properly flush the TLB when     completing, potentially leaving access to a physical page after it has been released to the page     allocator. A local attacker could use this to cause a denial of service (system crash), expose sensitive     information, or possibly execute arbitrary code. (CVE-2018-18281)

    Wei Wu discovered that the KVM implementation in the Linux kernel did not properly ensure that ioapics     were initialized. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2018-19407)

    It was discovered that the debug interface for the Linux kernel's HID subsystem did not properly perform     bounds checking in some situations. An attacker with access to debugfs could use this to cause a denial of     service or possibly gain additional privileges. (CVE-2018-9516)

The version of AOS installed on the remote host is prior to 5.16.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.16.0.1 advisory.

  - OpenSLP as used in ESXi and the Horizon DaaS appliances has a heap overwrite issue. VMware has evaluated     the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.
    (CVE-2019-5544)

  - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the     mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)

  - Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly     sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox     < 68, and Thunderbird < 60.8. (CVE-2019-11729)

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

  - An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an
    __blk_drain_queue() use-after-free because a certain error case is mishandled. (CVE-2018-20856)

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

The version of AOS installed on the remote host is prior to 5.17. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.17 advisory.

  - A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell     WiFi chip driver. The vulnerability allows 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. (CVE-2019-14901)

  - libImaging/PcxDecode.c in Pillow before 6.2.2 has a PCX P mode buffer overflow. (CVE-2020-5312)

  - An issue was discovered in Pillow before 6.2.0. When reading specially crafted invalid image files, the     library can either allocate very large amounts of memory or take an extremely long period of time to     process the image. (CVE-2019-16865)

  - Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly     sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox     < 68, and Thunderbird < 60.8. (CVE-2019-11729)

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

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

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

The following security bugs were fixed :

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic was uninitialized (bnc#1116841).

CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946).

CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714).

CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation (bnc#1118319).

CVE-2018-16862: A security flaw was found in the way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one (bnc#1117186).

CVE-2018-14625: A flaw was found where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients (bnc#1106615).

CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743).

CVE-2018-12232: In net/socket.c there is a race condition between fchownat and close in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr functions.
fchownat did not increment the file descriptor reference count, which allowed close to set the socket to NULL during fchownat's execution, leading to a NULL pointer dereference and system crash (bnc#1097593).

CVE-2018-18397: The userfaultfd implementation mishandled access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c (bnc#1117656).

CVE-2018-19854: An issue was discovered in the crypto_report_one() and related functions in crypto/crypto_user.c (the crypto user configuration API) do not fully initialize structures that are copied to userspace, potentially leaking sensitive memory to user programs.
NOTE: this is a CVE-2013-2547 regression but with easier exploitability because the attacker did not need a capability (however, the system must have the CONFIG_CRYPTO_USER kconfig option) (bnc#1118428).

CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769).

CVE-2017-5753: Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (bnc#1074578)

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