CVE-2025-55780: AI LLM developers should not underestimate Mupdf design flaw! (29-09-2025)
Preface: LLMs are built on machine learning: specifically, a type of neural network called a transformer model. How do LLMs read PDFs? The first step was to extract the text blocks from the PDF using pdfplumber . Each text block came with its coordinates, which allowed to analyze their spatial relationships. Next, I created a “window” around each text block…

Point of view – NVIDIA’s NVDebug tool, about CVE-2025-23342 and CVE-2025-23343. (12th Sep 2025)
Preface: Debug logs may contain user IDs and passwords to provide diagnostic information for failed login attempts, authentication failures, or to trace user activity within an application, but this is a significant security risk and should be avoided. Security best practices dictate that sensitive information like passwords should never be logged in cleartext. Instead, logging…
