Vulnerability from csaf_certbund - Published: 2021-07-29 22:00 - Updated: 2024-04-07 22:00Es existiert eine Schwachstelle in util-linux. Aufgrund eines Integer Overflows kann ein Pufferüberlauf, wenn Systemressourcen in einer Weise genutzt werden können, dass sie zu einer großen Datei in "/proc/sysvipc/sem" führen. Ein lokaler Angreifer kann diese Schwachstelle ausnutzen, um einen Denial of Service Zustand herbeizuführen. Zur erfolgreichen Ausnutzung ist eine Benutzeraktion erforderlich.
