The document describes an assembly exploit that allows unauthorized root privilege access through a buffer overflow, enabling hackers to manipulate addresses beyond the eip register. It mentions that the vecho command is vulnerable to such exploits, similar to the echo command. To prevent this, programmers should have included checks for the eip register to throw errors when accessing out-of-bounds addresses.

1. Write a short paragraph explaining what the exploit does in Assembly , and how it works. How
could the
programmer of vecho have prevented this from happening?
Solution
Exploit in assembly allows us to gain unauthorized root priviledge by using buffer overflow. It
allows hackers to gain access to addresses beyond the eip register. Exploits are generally used in
developing virus. The command vecho, which is similar to the echo command is vulnerable and
used in exploits.
The programmers of vecho should have checked for the address in the eip register and any
attempt to access addresses beyond it should have thrown an error.
