CVE-2019-15847

Es existiert eine Schwachstelle in gcc. Das POWER9-Backend in der GNU Compiler Collection (GCC) kann mehrere Aufrufe des __builtin_darn intrinsisch zu einem einzigen Aufruf optimieren und so die Entropie des Zufallszahlengenerators reduzieren. Ein Angreifer kann diese Schwachstelle ausnutzen, um Sicherheitsmechanismen zu umgehen.
