Ipchains buffer overflow with debian 2.2.10 Kernel. -------------------------------------------------- there is a buffer overflow hang in linux debian distributin kernel 2.2.10 with ipchains 1.3.8, 27-Oct-1998. here is the explanation. We tested with a linux running with debian above version of kernel and ipchains. first we setup the linux box to handle IP Masquerading as follows. ipchains -A forward -j MASQ -s 192.168.0.0/16 Then from a local workstation within the 192.168.0.0 network. We ssh to the linux box. and did the following $ping -f <ip.address> And we opend a another ssh session to the linux box and did the following $ping -l 6512121 <ip.address> After a few minutes. Ipchains hangs and the linux server hangs.. Ipchains-patch.gz will fix the problem. ---------------------- THE UNDERTAKER -> EFNET -> REAL CRACKING !!!REST IN PACE!!!!
