Vulnerability from csaf_certbund - Published: 2023-11-20 23:00 - Updated: 2025-01-12 23:00Summary
GnuTLS: Schwachstelle ermöglicht Offenlegung von Informationen
Severity
Mittel
Notes
Das BSI ist als Anbieter für die eigenen, zur Nutzung bereitgestellten Inhalte nach den allgemeinen Gesetzen verantwortlich. Nutzerinnen und Nutzer sind jedoch dafür verantwortlich, die Verwendung und/oder die Umsetzung der mit den Inhalten bereitgestellten Informationen sorgfältig im Einzelfall zu prüfen.
Produktbeschreibung: GnuTLS (GNU Transport Layer Security Library) ist eine im Quelltext frei verfügbare Bibliothek, die Secure Sockets Layer (SSL) und Transport Layer Security (TLS) implementiert.
Angriff: Ein entfernter, anonymer Angreifer kann eine Schwachstelle in GnuTLS ausnutzen, um Informationen offenzulegen.
Betroffene Betriebssysteme: - Linux
- UNIX
- Windows
Es besteht eine Schwachstelle in GnuTLS. Dieser Fehler besteht aufgrund der TLS-Antwortzeitunterschiede zwischen missgebildeten Chiffretexten und korrekten Chiffretexten, was zu einem Seitenkanalangriff führt, der Einblick in die verschlüsselten Daten ermöglicht. Ein entfernter Angreifer kann diese Schwachstelle ausnutzen, um vertrauliche Informationen offenzulegen.
