    Summary: network-manager vulnerability

    Details: Felix Wilhelm discovered that the NetworkManager internal DHCPv6 client incorrectly handled certain DHCPv6 messages. In non-default configurations where the internal DHCP client is enabled, an attacker on the same network could use this issue to cause NetworkManager to crash, resulting in a denial of service, or possibly execute arbitrary code.
