Platform (OCP), OpenShift ServiceMesh (OSSM), Red Hat OpenShift Jaeger (RHOSJ) and OpenShift Virtualization all bundle vulnerable versions of the golang standard library (stdlib). However, no component within each product utilizes the function xml.NewTokenDecoder which is a requirement to be vulnerable. Hence, all affected components are marked as \"Will not fix\". Additionally no OCP container has been listed, as nearly all available containers are compiled with an affected version of Go, but do not utilize the function xml.NewTokenDecoder.\nRed Hat Ceph Storage (RHCS), Red Hat Gluster Storage 3 and OpenShift Container Storage 4 also bundles a vulnerable version of golang standard library 'encoding/xml', but does not utilize the function xml.NewTokenDecoder, and hence this issue has been rated as having a security impact of Low.\nWithin regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.\nThe platform enforces hardening guidelines to ensure the most restrictive setting needed for operational requirements. Event logs are collected and processed for centralization, correlation, analysis, monitoring, reporting, alerting, and retention. This process ensures that audit logs are generated for specific events involving sensitive information, enabling capabilities like excessive CPU usage, long execution times, or processes consuming abnormal amounts of memory. Static code analysis and peer code review techniques are used to execute robust input validation and error-handling mechanisms to ensure all user inputs are thoroughly validated, preventing infinite loops caused by malformed or unexpected input, such as unbounded user input or unexpected null values that cause loops to never terminate. In the event of successful exploitation, process isolation limits the effect of an infinite loop to a single process rather than allowing it to consume all system resources.", "threat_severity": "Moderate"}
