What it is about

Go ist eine quelloffene Programmiersprache. Ein Angreifer kann mehrere Schwachstellen in Golang Go ausnutzen, um Speicherbeschädigungen zu verursachen, beliebigen Code auszuführen, Sicherheitsmaßnahmen zu umgehen, einen Denial-of-Service-Zustand auszulösen oder andere, nicht näher spezifizierte Angriffe durchzuführen.

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

  • Speicherbeschädigungen zu verursachen
  • beliebigen Code auszuführen
  • Sicherheitsmaßnahmen zu umgehen
  • einen Denial-of-Service-Zustand auszulösen oder andere, nicht näher spezifizierte Angriffe durchzuführen
