Test ID:1.3.6.1.4.1.25623.1.1.2.2020.2428
Category:Huawei EulerOS Local Security Checks
Title:Huawei EulerOS: Security Advisory for dpdk (EulerOS-SA-2020-2428)
Summary:The remote host is missing an update for the Huawei EulerOS; 'dpdk' package(s) announced via the EulerOS-SA-2020-2428 advisory.
Description:Summary:
The remote host is missing an update for the Huawei EulerOS
'dpdk' package(s) announced via the EulerOS-SA-2020-2428 advisory.

Vulnerability Insight:
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)

Affected Software/OS:
'dpdk' package(s) on Huawei EulerOS V2.0SP9(x86_64).

Solution:
Please install the updated package(s).
