CVE-2020-14040
Description
A denial of service vulnerability was found in the golang.org/x/text library. A library or application must use one of the vulnerable functions, such as unicode.Transform, transform.String, or transform.Byte, to be susceptible to this vulnerability. If an attacker is able to supply specific characters or strings to the vulnerable application, there is the potential to cause an infinite loop to occur using more memory, resulting in a denial of service.
Statement
OpenShift ServiceMesh (OSSM) 1.0 is Out Of Support Scope (OOSS) for Moderate and Low impact vulnerabilities. Jaeger was packaged with ServiceMesh in 1.0, and hence is also marked OOSS, but the Jaeger-Operator is a standalone product and is affected by this vulnerability.
Because Service Telemetry Framework does not directly use unicode.UTF16, no update will be provided at this time for STF's sg-core-container.
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.
