Summary
The remote host is missing an update to ipmasq announced via advisory DSA 389-1.
Insight
Insight
ipmasq is a package which simplifies configuration of Linux IP masquerading, a form of network address translation which allows a number of hosts to share a single public IP address. Due to use of certain improper filtering rules, traffic arriving on the external interface addressed for an internal host would be forwarded, regardless of whether it was associated with an established connection. This vulnerability could be exploited by an attacker capable of forwarding IP traffic with an arbitrary destination address to the external interface of a system with ipmasq installed. For the current stable distribution (woody) this problem has been fixed in version 3.5.10c. For the unstable distribution (sid) this problem has been fixed in version 3.5.12. We recommend that you update your ipmasq package.
