What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein lokaler Angreifer kann eine Schwachstelle in der glib Bibliothek von Red Hat Enterprise Linux ausnutzen, um einen Denial of Service Angriff durchzuführen und weitere nicht spezifizierte Auswirkungen zu verursachen.
Under what conditions?
Only with access to the device or an account on it. Often the second step after a phishing email.
What can happen in the worst case
An attacker could use the vulnerability to
- einen Denial of Service Angriff durchzuführen
- weitere nicht spezifizierte Auswirkungen zu verursachen
Am I affected?

- Red Hat Enterprise Linux
- Ubuntu Linux
- SUSE Linux
- Oracle Linux
- RESF Rocky Linux
- IBM App Connect Enterprise
- Red Hat Enterprise Linux 9
- IBM TXSeries for multiplatforms
- Red Hat OpenShift Container Platform <4.16.57
- Red Hat OpenShift Container Platform <4.14.62
- Dell NetWorker vProxy <19.13.0.3
- Red Hat OpenShift Container Platform <4.15.62
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Red Hat OpenShift Container Platform 4.16.57
- Red Hat OpenShift Container Platform 4.14.62
