Update go net package

[esimkowitz]

There's a potential DDoS vulnerability in the older version of the net package that we were using. It likely isn't something that would impact us, but we should still update for posterity.

Walkthrough

The pull request involves updates to the go.mod file, focusing on modifying dependency versions and module replacements. The changes include three primary modifications:

1. An update to the golang.org/x/net dependency, incrementing its version from v0.29.0 to v0.33.0 as an indirect dependency.

2. Replacement of the github.com/kevinburke/ssh_config module with github.com/wavetermdev/ssh_config, using a specific commit reference v0.0.0-20241219203747-6409e4292f34.

3. Substitution of the github.com/creack/pty module with github.com/photostorm/pty, using the version v1.1.19-0.20230903182454-31354506054b.

These changes represent routine dependency management in the project, involving version updates and module replacements. The modifications do not introduce new dependencies or fundamentally alter the project's dependency structure, but instead update existing module references to potentially newer or alternative implementations.

48-48: Verify golang.org/x/net version update for security and compatibility

The update from v0.29.0 to v0.33.0 aligns with the PR objective to address the DDoS vulnerability. Let's verify this version.

✅ Verification successful

✅ Version v0.33.0 is appropriate and addresses the latest security vulnerability

The update to golang.org/x/net v0.33.0 is verified to be secure and appropriate because:

• It's the first patched version that fixes the latest HIGH severity vulnerability (published Dec 18, 2024) related to "Non-linear parsing of case-insensitive content"
• It inherently includes fixes for all previous vulnerabilities found in older versions
• The version aligns perfectly with the PR's objective of addressing the DDoS vulnerability

Line range hint 50-54: Review security implications of using forked dependencies

While using forked versions of ssh_config and pty may be necessary, it's important to verify the security implications:

1. The wavetermdev fork of ssh_config uses a very recent commit (December 2023)
2. The photostorm fork of pty uses a specific commit from September 2023

Consider:

1. Documenting the reasons for using these specific forks in the repository
2. Setting up a process to regularly review and update these dependencies
3. Adding security scanning for the forked dependencies to your CI pipeline

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
