What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux ausnutzen, um Administratorrechte zu erlangen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren und einen Denial-of-Service-Zustand auszulösen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- Administratorrechte zu erlangen
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren
- einen Denial-of-Service-Zustand auszulösen
