Severity
Niedrig

Produktbeschreibung: Der Kernel stellt den Kern des Linux Betriebssystems dar.
Angriff: Ein lokaler Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - UNIX
- Linux
Es existiert eine Schwachstelle im Linux Kernel in Verbindung mit dem netfilter Code für iptables Unterstützung. Diese Schwachstelle beruht in der "mark_source_chains" Funktion in [net/ipv4/netfilter/ip_tables.c], [net/ipv4/netfilter/arp_tables.c] und [net/ipv6/netfilter/ip6_tables.c] und wird durch eine Speicherverletzung verursacht. Ein lokaler Angreifer kann diese Schwachstelle über PF_INET Sockets ausnutzen, wenn unprivilegierte Benutzer Namespaces verfügbar sind (CONFIG_USER_NS=y). In der Folge kann ein Angreifer einen Denial of Service des Systems herbeiführen.
Es existiert eine Integer-Überlauf Schwachstelle im Linux Kernel. Diese Schwachstelle beruht in der "xt_alloc_table_info" Funktion in [net/netfilter/x_tables.c] und wird durch eine Speicherverletzung verursacht. Ein lokaler Angreifer kann diese Schwachstelle ausnutzen, um einen Denial of Service Zustand herbeiführen. Von dieser Schwachstelle sind nur 32-bit Systeme betroffen.
