Red Hat Satellite dient als zentrale Stelle für das Management, die Verteilung von Updates in Netzwerken mit Red Hat Enterprise Linux Systemen. Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, authentisierter Angreifer kann eine Schwachstelle in Red Hat Satellite für Red Hat Enterprise Linux ausnutzen, um Sicherheitsmaßnahmen zu umgehen und so vertrauliche Informationen offenzulegen.

Under what conditions?

Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.

What can happen in the worst case

An attacker could use the vulnerability to
