Version 8.10 Hot Fix 4 to address the vulnerabilities in VMware
Patches were made available for the vulnerabilities in VMware, which should be upgraded by users to avoid leaving the product and device exposed to hackers.
Vulnerabilities are a common and major cause of exploitation as hackers are always on the lookout for flaws that lets them make their way into systems. One unpatched system endangers the entire network of even patched software including devices that are connected to it.
Called hot fix 4 (91852), VMware made patches available for all the users. The fixes page was updated on May 11, 2023, and it addressed the following issues:
- VMware chargeback bills creating inaccurate results.
- Bills showing only Tier 1 value excluding Tier 2 on vapp.

To make sure the upgrade is completed, one may have to clear the browser caches and see that the page is refreshed.
Vulnerability management and cybersecurity
According to Dan Richings, SVP – Global Presales and Solutions Engineering at Adaptiva, companies face several challenges when it comes to patch management.
One challenge is the overwhelming influx of patches, leading to a backlog that needs prioritization based on usage and security severity. Remote work and the use of personal devices add complexity to securing and monitoring updates.
Communication issues arise when different IT teams handle various tasks, and slow change management processes and flawed patches further impede the patching process. Additionally, many organizations still rely on manual patching, which consumes significant time and resources.
