Release Notes: VMware NSX 4.2.1.1 Release Notes

While NSX 4.2.1 brought several improvements, NSX 4.2.1.1 takes things further with targeted fixes and enhancements. Here's a breakdown of what’s worth noting:

1. Security Patches for Critical Vulnerabilities

The most significant difference between NSX 4.2.1 and NSX 4.2.1.1 is the resolution of several critical security vulnerabilities. Specifically, NSX 4.2.1.1 addresses:

  • CVE-2024-38818

  • CVE-2024-38817

  • CVE-2024-38815

These vulnerabilities were recently documented in VMSA-2024-0020, VMware’s security advisory, and could potentially expose your infrastructure to various attack vectors. NSX 4.2.1.1 offers patches for these vulnerabilities, making it a more secure release than its predecessor. If security is a priority in your environment (as it should be), upgrading to NSX 4.2.1.1 is critical to protecting your VMware ecosystem.

2. Additional Bug Fixes and Resolved Issues

Alongside the security updates, NSX 4.2.1.1 also comes with a range of bug fixes that weren’t addressed in NSX 4.2.1. These fixes span various functionality areas, enhancing overall performance and stability.

For those already using NSX 4.2.1, the release notes for NSX 4.2.1.1 list the resolved issues, which can give you insight into the bugs and glitches that may have impacted your environment. Whether it’s network performance, troubleshooting, or system stability, NSX 4.2.1.1 promises an improved user experience with fewer issues to manage.

3. Express Release: Speedy Fixes for Immediate Concerns

NSX 4.2.1.1 has been labelled as an "Express Release," which implies that VMware released it quickly to address immediate security and functionality concerns. It is not uncommon for vulnerabilities to be discovered that could potentially impact the safety and performance of your systems.

If you’re looking for a patch release that prioritises security and bug fixes over new features, NSX 4.2.1.1 is the way to go. VMware’s responsiveness to these vulnerabilities shows that it actively monitors their products and takes quick action when needed. 

 

Why You Should Consider Upgrading to NSX 4.2.1.1

If you’re currently running NSX 4.2.1, it’s highly recommended that you upgrade to NSX 4.2.1.1. Here’s why:

  • Security First: CVE-2024-38818, CVE-2024-38817, and CVE-2024-38815 are not just numbers—they represent real vulnerabilities that could potentially compromise your environment. By upgrading, you ensure that your systems are protected from these exploits.

  • More Stability and Fewer Bugs: NSX 4.2.1.1 includes important bug fixes that contribute to a smoother, more reliable operation. If you’ve encountered issues in NSX 4.2.1, upgrading may help resolve these problems, making your networking environment more stable.

  • Quick Response to Critical Issues: As an "Express Release," NSX 4.2.1.1 is about fast fixes for urgent concerns. If you rely on VMware NSX for mission-critical applications, this quick patch ensures you're running a more secure and bug-free version.

Final Thoughts
