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