An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.

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

  - A flaw was found in dpdk in versions before 18.11.10     and before 19.11.5. A flawed bounds checking in the     copy_data function leads to a buffer overflow allowing     an attacker in a virtual machine to write arbitrary     data to any address in the vhost_crypto application.
    The highest threat from this vulnerability is to data     confidentiality and integrity as well as system     availability.(CVE-2020-14374)

  - A flaw was found in dpdk in versions before 18.11.10     and before 19.11.5. Virtio ring descriptors, and the     data they describe are in a region of memory accessible     by from both the virtual machine and the host. An     attacker in a VM can change the contents of the memory     after vhost_crypto has validated it. The highest threat     from this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-14375)

  - A flaw was found in dpdk in versions before 18.11.10     and before 19.11.5. A lack of bounds checking when     copying iv_data from the VM guest memory into host     memory can lead to a large buffer overflow. The highest     threat from this vulnerability is to data     confidentiality and integrity as well as system     availability.(CVE-2020-14376)

  - A flaw was found in dpdk in versions before 18.11.10     and before 19.11.5. A complete lack of validation of     attacker-controlled parameters can lead to a buffer     over read. The results of the over read are then     written back to the guest virtual machine memory. This     vulnerability can be used by an attacker in a virtual     machine to read significant amounts of host memory. The     highest threat from this vulnerability is to data     confidentiality and system     availability.(CVE-2020-14377)

  - An integer underflow in dpdk versions before 18.11.10     and before 19.11.5 in the `move_desc` function can lead     to large amounts of CPU cycles being eaten up in a long     running loop. An attacker could cause `move_desc` to     get stuck in a 4,294,967,295-count iteration loop.
    Depending on how `vhost_crypto` is being used this     could prevent other VMs or network tasks from being     serviced by the busy DPDK lcore for an extended     period.(CVE-2020-14378)

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4550-1 advisory.

    Ryan Hall discovered that DPDK incorrectly handled vhost crypto. An attacker inside a guest could use     these issues to perform multiple attacks, including denial of service attacks, obtaining sensitive     information from the host, and possibly executing arbitrary code on the host.

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

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