Vulnerability Research – Null pointer dereference in Curl

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.

The Art of Fuzzing – Smart Contracts

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.
