What is CVE-2024-50609?

A vulnerability has been identified in Fluent Bit version 3.1.9, specifically related to the OpenTelemetry input plugin. When this plugin is operational and listening on a specified IP address and port, it is susceptible to a Denial of Service attack. This occurs when a malicious actor sends a packet with a Content-Length header set to zero. Due to improper handling of the zero-length content, the server may crash as it encounters a NULL pointer dereference during processing. This vulnerability highlights the need for robust input handling mechanisms in server applications to prevent potential exploitation.
