In its latest Patch Tuesday release, Microsoft has issued security updates for a total of 150 flaws, with a significant focus on addressing remote code execution (RCE) bugs. Taking center stage among the vulnerabilities, 67 RCE flaws were identified, with a notable concentration found within Microsoft SQL drivers, hinting at a potential common flaw.

While only three critical vulnerabilities were addressed in today's Patch Tuesday, the extensive number of RCE bugs highlights Microsoft's commitment to bolstering system security. Additionally, this month's release includes fixes for 26 Secure Boot bypasses, two of which were identified in devices manufactured by Lenovo.

However, it's important to note that the count of 150 flaws does not include the five Microsoft Edge flaws that were already addressed on April 4th, as well as two Mariner flaws. Mariner, an open-source Linux distribution developed by Microsoft for its Azure services, received the necessary updates to enhance its security measures.

Sadly, the April 2024 Patch Tuesday did not provide any fixes for zero-day vulnerabilities that were disclosed by Microsoft. Nevertheless, researchers from Varonis have discovered two zero-day vulnerabilities in Microsoft SharePoint. These flaws can make it more challenging to detect when files are downloaded from servers. Microsoft has yet to assign CVEs to these vulnerabilities, and they have been added to the patching backlog, leaving their mitigation timelines uncertain.

Several vendors also released security updates and vulnerability advisories in April 2024 to enhance the overall cybersecurity landscape. Unfortunately, the provided information does not specify the names of these vendors or the vulnerabilities they addressed.

For more detailed information on each resolved vulnerability and the systems affected, readers can refer to the comprehensive report provided by Microsoft.

Overall, Microsoft's April 2024 Patch Tuesday highlights the company's continuous efforts to deliver timely and significant security updates, with a strong focus on tackling remote code execution bugs and addressing vulnerabilities in widely-used drivers and services.
