Converting Vulnerabilities into Exploitation Primitives
Fuzzing is a popular approach for producing inputs that cause a program to crash. In the case of heap overflow vulnerabilities, to use them in an exploit it is necessary to determine what can be corrupted by the overflow, how to manipulate the heap to ensure that this corruption occurs, and then how to make use of the corrupted data. The goal of this project is to investigate how to automate this process and develop a system that can convert a vulnerability trigger into into a new input that can be used as part of an exploit to hijack the control flow of the target.
The proposed projects will expand on the work of the lidted Dphil studen (Sean Heelan)
