Summary

The vulnerability in F5 BIG-IP systems occurs when certain versions process a specially crafted gzip bomb payload. When a virtual server leverages the inflate functionality, it can lead to a fatal error, potentially causing the Traffic Management Microkernel (TMM) to generate a core file. This situation may disrupt normal operations and service availability, thereby posing a significant risk for affected systems.
