‼️ Apache Patches Critical HTTP/2 Flaw Allowing Remote Code Execution on Web Servers Details: cybersecuritynews.com/apache… Apache has fixed a critical bug in its HTTP/2 module that could let a remote attacker run code on a web server. The flaw is tracked as CVE-2026-119618 and affects mod_http2. The fix came on November 11, 2026, in Apache HTTP Server 2.4.71. The flaw sits in a function called assign_headers(). Apache says it is a concurrency problem, where shared resources are used without proper locking. Apache HTTP Server versions 2.4.55 through 2.4.70 are affected. The most suitable mitigation is to upgrade to Apache HTTP Server 2.4.71 as soon as you can. Start with public-facing servers that have HTTP/2 turned on. #CybersecurityNews

Today I'm getting into cgroups for my next article. The last one was about namespaces, which decide what a process can see. Cgroups decide how much it can use. One thing that is kinda surprising is how you interact with cgroups, through the filesystem, generating a new cgroup is as easy as running a "mkdir" command. And limiting the number of processes just an "echo" command. I'll talk about the cgroups, the controllers, and how they are shaped and access in the kernel. The article will be available this Monday.

This is about as easy as I've seen when it comes to hooking up a RAG pipeline using vectors in your Oracle AI Database. SQLcl offers a single command to scoop up your unstructured data into a vector table, and then an MCP tool to context retrieve the info back to your agent. thatjeffsmith.com/archive/20…
