CVE-2020-10675
Description
A flaw was found in golang-github-buger-jsonparser. The Library API in buger jsonparser through 2019-12-04 allows attackers to cause a denial of service (infinite loop) via a delete call. The highest threat from this vulnerability is to system availability.
Statement
The OpenShift Container Platform 4 (OCP) containers, file-integrity-rhel8-operator, cnf-tests-rhel8 and ose-container-networking-plugins-rhel8, do have some references to github.com/buger/jsonparser, mainly in their go.sum files. However, it is not included in the final go build. It is also a dependency of the dependency github.com/containernetworking/plugins which only includes buger/jsonparse when compiling for Windows, which these containers do not. Hence, the associated containers have been marked not affected.
OpenShift Virtualization cnv-containernetworking-plugins container depends on github.com/buger/jsonparser only when built for Windows, which it is not, thus it is not affected. Other OpenshiftVirtualization containers (virt-api, virt-controller, virt-handler, virt-launcher, virt-operator, kubernetes-nmstate-handler, ovs-cni-marker, ovs-cni-plugin, kubemacpool, hyperconverged-cluster-operator) have references to github.com/buger/jsonparser, however, it is not included in the final go build.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Amplification
An infinite loop will cause unexpected consumption of resources, such as CPU cycles or memory. The software's operation may slow down, or cause a long time to respond.
