Thought Spectre is history? It’s still alive, and Kicking
Two more vulnerabilities uncovered in OpenSSL
A maliciously created X509 certificate with specially crafted Issuer and Serial Numbers fields can potentially cause OpenSSL failure that in turn spits out a NULL value. This can cause a crash from the application calling the function. OpenSSL does not call functions; only the third-party application is at risk of the exploit. Head over to the blog and find out what KernelCare is doing to alleviate this persistent threat.
The IoT and industrial control systems (ICS) are revolutionizing how industries automate by offering low power and low-cost computing. This comes with a price. ICS devices running on the IoT can be a management and security nightmare. Microsoft has stepped in to offer the Azure IoT Hub helps organizations catalog, manage, and integrate large fleets of IoT devices. In closing a service gap, we are excited to announce that KernelCare for IoT fully integrates with Device Update for the Azure IoT Hub from Microsoft. Find out more here.
Just in case you missed it, we released AlmaLinux OS, a new community-driven distro on 30 March to much fanfare. You can install KernelCare on the AlmaLinux OS for security fixes with no downtime. Always available and always secure.
