The heart of the vulnerability lies within the code of the idn module, where the function idn_decode() becomes the focal point of concern. This function, when called, inadvertently passes a null value to the *decoded pointer, which later encounters issues during execution, as evidenced by the Curl_idn_free() function.
In this article, we explore the fascinating world of smart contract auditing and vulnerability detection through Fuzzing. Smart contracts, self-executing programs operating on blockchain platforms, have revolutionized decentralized applications. To ensure their robustness, auditing becomes a crucial step before deploying smart contracts.
This fuzzing introduction cover all the essentials one should know about the art of fuzzing. It explain major concept and illustrate it with and hands-on exercise the reader can follow. In conclusion some hints are given on how to hunt for bugs with fuzzing
