[DSA389] DSA-389-1 ipmasq |
||
DSA-389-1 ipmasq Detailed Explanation for this Vulnerability Assessment ipmasq is a package which simplifies configuration of Linux IP masquerading, a form of network address translation which permits 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 a possible hacker 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.
