Skupper-router: skupper-router: unbounded recursion in amqp field parser leads to denial of service

Assigner: redhat
Reserved: 10.09.2026 Published: 10.09.2026 Updated: 10.09.2026

A flaw was found in the skupper-router component of Red Hat Service Interconnect, which is used to provide secure communication between distributed services. The issue occurs when the router processes a specially crafted network message using its AMQP field parser. Due to a lack of bounds on recursion during parsing, the router can run out of stack memory and crash, leading to a denial of service for the interconnected network.
