What it is about

Adobe Acrobat ist ein Programm für die Erstellung und Betrachtung von Dokumenten im Portable Document Format (PDF). Adobe Reader ist ein Programm für die Anzeige von Dokumenten im Portable Document Format (PDF). Ein lokaler Angreifer kann mehrere Schwachstellen in Adobe Acrobat und Adobe Acrobat Reader ausnutzen, um beliebigen Code auszuführen, Berechtigungen zu erweitern, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, 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 Code auszuführen
  • Berechtigungen zu erweitern
  • Sicherheitsmaßnahmen zu umgehen
  • Daten zu manipulieren
  • vertrauliche Informationen offenzulegen oder einen Denial-of-Service-Zustand zu verursachen
