Coalesce Model to Prevent Format String Attacks
Format string attacks cause serious security problems in the field of software security in computer world. Testing and implementation against to Format String vulnerabilities can avoid result due to working of Format String Bugs. In this paper, we have proposed eight novel approaches to prevent format string attacks and combination of these approaches named as Coalesce Model. With the help of this model we check our coding in such a manner that no any type of format string attacks occurs. We check the system implementation of any applications with the help of coalesce model against corruption of application states, and giving the control to attacker. Our work addresses Format String vulnerabilities related to ANSI C library. The result indicates that the proposed model is effective to testing of Format String Vulnerability.
