CVE-2024-43499 (opens in a new tab)How to fix?
Upgrade System.Formats.Nrbf to version 9.0.0 or higher.
Overview
System.Formats.Nrbf is a package that exposes only one component: NrbfDecoder: a stateless, forward-only decoder class that can decode .NET Remoting Binary Format (NRBF) binary data from a stream.
Affected versions of this package are vulnerable to Unchecked Input for Loop Condition via the NrbfDecoder component, due to jagged arrays in the payload that can contain cycles. An attacker can cause the application to crash or become unresponsive by sending specially crafted input.
Note:
By default, .NET console apps and web apps do not reference the NrbfDecoder component.
