CVE-2020-28851
Description
A flaw was found in golang.org. In x/text, an "index out of range" panic occurs in language.ParseAcceptLanguage while parsing the -u- extension.
Statement
Below Red Hat products include the affected version of 'golang.org/x/text', however the language package is not being used and hence they are rated as having a security impact of Low. A future update may address this issue.
- Red Hat OpenShift Container Storage 4
- OpenShift ServiceMesh (OSSM)
- Red Hat Gluster Storage 3
- Windows Container Support for Red Hat OpenShift
Only three components in OpenShift Container Platform include the affected package, 'golang.org/x/text/language' , the installer, baremetal installer and thanos container images. All other components that include a version of 'golang.org/x/text' do not include the 'language' package and are therefore not affected.

Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
