What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein lokaler Angreifer kann eine Schwachstelle in Red Hat Enterprise Linux ausnutzen, um beliebigen Programmcode auszuführen, vertrauliche Informationen offenzulegen oder einen Denial-of-Service-Zustand 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
- beliebigen Programmcode auszuführen
- vertrauliche Informationen offenzulegen oder einen Denial-of-Service-Zustand zu verursachen
Am I affected?
