Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a critical security enhancement by adding a directory traversal check during the extraction of binaries. This measure ensures that archive entries containing '..' are identified and rejected, thereby preventing potential vulnerabilities where malicious files could be written to arbitrary locations on the filesystem.

Highlights

• Security Enhancement: Implemented a directory traversal check within the extractBinary function to prevent malicious archive entries from writing files outside the intended target directory.

Code Review

This pull request adds a security check to prevent directory traversal vulnerabilities when extracting zip archives. The added check is a good first step, but it's incomplete and doesn't protect against all forms of path traversal (like absolute paths). I've provided a suggestion for a more robust implementation based on Go security best practices.
