Spike Spiegel has discovered a vulnerability in Ganglia which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error within the process_path function in gmetad/server.c. This can be exploited to cause a stack-based buffer overflow by e.g. sending a specially crafted message to the gmetad service. The vulnerability is confirmed in version 3.1.1. Other versions may also be affected.
