Background
sized-chunks is a crate for Rust that provides a Chunk implementation. This implementation allows for the creation of chunks with a specified size. However, versions up to 0.6.2 of the crate have a vulnerability where the array size is not properly checked when constructed with pair(). This oversight can lead to potential security issues.
Vulnerability Detail
The vulnerability in sized-chunks arises from the lack of array size validation in the Chunk implementation. When constructed with pair(), the array size is not properly checked, which can result in memory corruption or other security vulnerabilities. An attacker could potentially exploit this vulnerability to execute arbitrary code, cause a denial of service, or gain unauthorized access to sensitive information.
