Descriptions
A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses.
Se encontró una falla en Open vSwitch que permite que los paquetes de anuncios de vecinos ICMPv6 entre máquinas virtuales omitan las reglas de OpenFlow. Este problema puede permitir que un atacante local cree paquetes especialmente manipulados con un campo de dirección IP de destino modificado o falsificado que puede redirigir el tráfico ICMPv6 a direcciones IP arbitrarias.
