Google has released an update for its Chrome browser to patch six security vulnerabilities including one zero-day.

### Summary A Denial of Service (DoS) vulnerability exists in the file processing logic when reading a file on endpoint `Filebrowser-Server-IP:PORT/files/{file-name}` . While the server correctly handles and stores uploaded files, it attempts to load the entire content into memory during read operations without size checks or resource limits. This allows an authenticated user to upload a large file and trigger uncontrolled memory consumption on read, potentially crashing the server and making it unresponsive. ### Details The endpoint ` /api/resources/{file-name}` accepts `PUT` requests with plain text file content. Uploading an extremely large file (e.g., ~1.5 GB) succeeds without issue. However, when the server attempts to open and read this file, it performs the read operation in an unbounded or inefficient way, leading to excessive memory usage. This approach attempts to read the entire file into memory at once. For large files, this causes memory exhaustion resulting in a cras...

When you subscribe to Red Hat Enterprise Linux (RHEL), you get security fixes for Common Vulnerabilities and Exposures (CVE). As defined in the RHEL Life Cycle Policy, we classify any issue rated with a Common Vulnerability Scoring System score of 7.0 or higher as Critical, Important or Moderate. Our enhanced support plans (RHEL Extended Life Cycle Support, Extended Update Support, and Enhanced Extended Update Support) include similar coverage. But compliance in finance, healthcare, telecommunications, the public sector and other highly regulated industries may demand fixes and patches outsid

Model Context Protocol (MCP) is a powerful protocol from Anthropic that defines how to connect large language models (LLMs) to external tools. It has quickly gained traction due to its ease of use and the benefits it adds in our use of AI. In this article we'll cover some of the potential security risks you'll encounter with MCP and how you can approach mitigating them.How MCP worksMCP does not directly connect LLMs with tools. The MCP client component accesses the LLM, and the MCP server component accesses the tools. One MCP client has access to one or more MCP servers. Users may connect any
