Dr. Blahbah has implemented a system with an 8-bit random canary that is used to de tect and prevent stack-based buffer overflow attacks. Describe an effective attack against Dr. Blahbah's system and analyze its likelihood of success
What will be an ideal response?
An 8-bit canary only provides 256 possible canary values, so an attacker can
try all possibilities in a fairly short amount of time. As soon as one of them has succeeded,
he has compromised the system, and each one has a pretty good, one out of 256 chance, of
succeeding.
