ipmasq Incorrect Packet Forwarding Default Ruleset Vulnerability
Debian has reported that the firewall rules configured by ipmasq may result in incorrect forwarding of traffic on the gateway host. According to the report, any traffic destined for internal hosts arriving at the external interface of the gateway will be forwarded to the destination host on the internal network regardless of whether the packet can be associated with an established connection or not. This behavior is incorrect and may result in attackers gaining unauthorized access to internal and potentially more vulnerable hosts. |
