+ BUGTRAQ:20020508 [CARTSA-20020402] Linux Netfilter NAT/ICMP code information leak
+ REDHAT:RHSA-2002:086

+ XF: linux-netfilter-information-leak(9043)
+ BID:4699
+Description:
+ The Network Address Translation (NAT) capability for Netfilter ("iptables")
+ 1.2.6a and earlier leaks translated IP addresses in ICMP error messages.
+Notes:
+ There's a patch here:
+ http://www.securityfocus.com/bid/4699
+ But it doesn't appear to have gone upstream. It doesn't look like RedHat
+ or Mandrake fixed it either; instead, they suggest a workaround:
+ http://rhn.redhat.com/errata/RHSA-2002-086.html
+ http://archives.mandrivalinux.com/security-announce/2002-02/msg00025.html
+ .
+ dannf> We plan to "fix" this by recommending the workaround as well.
+ horms> I believe that this problem was fixed as part of the following
+ horms> patch that was incuded in 2.6.11
+ horms> http://www.kernel.org/git/?p=linux/kernel/git/tglx/history.git;a=commitdiff;h=1e69ba3fa29b13fe5229d6e325aee91ae5abe298
+ horms> However I believe a related bug was introduced by the following
+ horms> patch, also included in 2.6.11
+ horms> http://www.kernel.org/git/?p=linux/kernel/git/tglx/history.git;a=commitdiff;h=8d5f3377d48c74df38990688f09e773887ba4eb5
+ horms> This new bugs allows discloser of the IP address of intermedate
+ horms> hops between the NATing box and the NAT'd box.
+ horms> This is easily demonstrated using tcptraceroute
+ horms> 1 10.0.1.7 61.524 ms 93.081 ms 22.982 ms
+ horms> 2 192.168.1.254 72.099 ms 66.899 ms 67.599 ms
+ horms> 3 10.0.1.7 [open] 67.188 ms 105.974 ms 104.873 ms
+ horms> I also believe that pretty much all kernels disclose
+ horms> enough information to work out if DNAT is in use or not.
+ horms> I wrote a long mail about this to netfilter-devel and will
+ horms> put a link here when it shows up
+ horms> In the mean time: (Message-ID: <20060202113824.GA4399@verge.net.au>)
+ horms> Given this seems to be an ongoing suite of problems, with little
+ horms> hope of a final solution, I'm marking it as ignore for all
+ horms> woody and sarge kernels, many of which i have reproduced the
+ horms> problem on allong with upstream's 2.4 (~2.4.33-pre1)
