ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs
CVE: CVE-2020-16845
Component: golang
CWE: CWE-835
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2020-08-06T00:00:00+00:00

A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The highest threat from this vulnerability is to system availability.

Statement: OpenShift Container Platform (OCP), OpenShift ServiceMesh (OSSM), RedHat OpenShift Jaeger (RHOSJ) and OpenShift Virtualization components are primarily written in Go, meaning that any component using the encoding/binary package includes the vulnerable code. The affected components are behind OpenShift OAuth authentication, therefore the impact is low.

Red Hat Gluster Storage 3, Red Hat OpenShift Container Storage 4 and Red Hat Ceph Storage (3 and 4)  components are built with the affected version of Go, however the vulnerable functionality is currently not used by these products and hence this issue has been rated as having a security impact of Low.
