Missing Release of Memory after Effective Lifetime

Overview Affected versions of this package are vulnerable to Missing Release of Memory after Effective Lifetime via the processdebuginfo function in the dwarf.c file. An attacker can cause resource exhaustion by triggering repeated processing of specially crafted DWARF sections. Remediation A fix...

Microsoft Sentinel data lake: Unify signals, cut costs, and power agentic AI

You can’t protect what you can’t see. Security operations teams have long been faced with the challenge of managing massive, fast-growing datasets, and the cost of scaling traditional data management tools to handle these data volumes has become unsustainable. We’re evolving our industry-leading...
