It’s the second Tuesday of the month, and Adobe and Microsoft have released a fresh crop of security updates. Take a break from your other activities and join us as we review the details of their latest advisories. If you’d rather watch the full video recap covering the entire release, you can check it out here:
Adobe Patches for March 2024
For March, Adobe released six patches addressing 56 vulnerabilities in Adobe Experience Manager, Premiere Pro, ColdFusion, Adobe Bridge, Lightroom, and Adobe Animate. Two of these bugs were submitted through the ZDI Program. The largest is the update for Experience Manager, which addresses 44 CVEs.

[CRITICAL] Another Patch Tuesday with no zero-days, only two critical vulnerabilities disclosed by Microsoft
For the second month in 2024, there are no actively exploited vulnerabilities included in this month’s security update from Microsoft.
March’s Patch Tuesday is relatively light, containing 60 vulnerabilities — only two labeled “critical.” Last month’s Patch Tuesday included more than 70 security vulnerabilities affecting Microsoft products, and there were even fewer in January and December, especially when compared to 2023.
Still, both critical vulnerabilities addressed this month are notable because they affect Windows Hyper-V, potentially allowing an adversary to target a host machine from a virtual machine environment.
All other vulnerabilities Microsoft disclosed Tuesday are considered to be of “important” severity.
