What it is about

Virtualization ist eine Virtualisierungslösung von Red Hat, die die simultane Ausführung von verschiedenen Betriebssystemen auf einem Host-System ermöglicht. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat Virtualization ausnutzen, um einen Denial of Service Angriff durchzuführen.

Under what conditions?

Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.

What can happen in the worst case

An attacker could use the vulnerability to

• einen Denial of Service Angriff durchzuführen

Am I affected?

Affected according to the BSI:

• Debian Linux
• Red Hat Enterprise Linux
• F5 BIG-IP
• Red Hat Virtualization <ovirt-4.4.6
• IBM MQ
• IBM QRadar SIEM
• Red Hat OpenShift Container Platform
• IBM Business Automation Workflow
• Red Hat OpenShift GitOps <1.19.4
• Red Hat OpenShift Container Platform <4.18.43
• IBM Storage Scale <5.2.3.8
• IBM Storage Scale <6.0.1.0

and 2 more

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

• Red Hat Virtualization ovirt-4.4.6
• Red Hat OpenShift GitOps 1.19.4
• Red Hat OpenShift Container Platform 4.18.43
• IBM Storage Scale 5.2.3.8
• IBM Storage Scale 6.0.1.0
• IBM Cognos Analytics 12.1.3 FP2
• IBM Cognos Analytics 12.0.4 FP3

Is the vulnerability already being exploited?

None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
