Seq Segment Fault.

[Ryan Whited]

Here is my code.

#!/bin/bash

echo "Add directions here."

read  URL
read  NUM1
read  NUM2
read  EXT
echo "Please choose a folder name."
read NAM
mkdir $HOME/$NAM
cd $HOME/$NAM


for i in $(seq -w $NUM1 $NUM2); do wget "$URL${i}$EXT"; done

I was testing out my script, and I came across an instance where I had
a large "i" (it started at 0000000000 and went to 9999999999). It
processed for a few minutes (my poor intel atom) and returned with a
"Segmentation fault". From what I know from Assembly, I think this is
a buffer overflow which could allow for malicious code injection.
Please let me know if I can be of further assistance.
