What it is about
Rsync ist ein Tool, um Dateien und Verzeichnisse zu synchronisieren. Ein Angreifer kann mehrere Schwachstellen in Rsync ausnutzen, um seine Privilegien zu erhöhen, beliebigen Code auszuführen, Daten offenzulegen oder zu manipulieren, Sicherheitsmaßnahmen zu umgehen oder Denial-of-Service-Zustände herbeizuführen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
