Summary

Red Enterprise Linux Advanced Virtualization: Mehrere Schwachstellen

Severity

Hoch

Scope

25 vulnerabilities in this advisory, including CVE-2021-39252.

CVE-2021-39252

In Red Enterprise Linux Advanced Virtualization existieren mehrere Schwachstellen in den QEMU, libvirt und ntfs-3g Komponenten. Die Ursachen sind Pufferüberläufe, Endlosschleifen, unsichere Konfigurationen und Überprüfungen und "Out of Bounds" Zugriffe. Ein entfernter oder lokaler, authentisierter Angreifer kann diese Schwachstellen ausnutzen, um einen Denial of Service zu verursachen, Sicherheitsvorkehrungen zu umgehen, beliebigen Code auszuführen und Informationen offenzulegen. Zur Ausnutzung einiger dieser Schwachstellen ist eine Benutzeraktion erforderlich.
