Microsoft Corp. today issued updates to plug at least 974 security holes in its Windows operating systems and other software, by far its biggest single patch batch ever. Microsoft says artificial intelligence is helping to speed the discovery of vulnerabilities, but security experts warn that many organizations already are struggling to prioritize the more human-intensive endeavor of testing and deploying so many fixes each month.
The EU Cyber Resilience Act's vulnerability reporting requirements take effect September 11, giving software vendors as little as 24 hours to report actively exploited flaws.

In the last six months, Chainguard doubled its output from 500 million to more than 1 billion container build manifests. We also surpassed 3,000 unique container images and 675,000 image versions in our catalog. Those are the headline numbers, but I want to share what's actually behind them. The number itself is less interesting than the system that produced it, and why we had to fundamentally…
A flaw in FreeIPA lets a client that has never logged in create a Kerberos identity of its own choosing in the directory and end up in the administrators group, Red Hat says.
