Ganglia is a scalable distributed monitoring system for clusters and grids.
Spike Spiegel reported a stack-based buffer overflow in the process_path() function when processing overly long pathnames in gmetad/server.c.
A remote attacker could send a specially crafted request to the gmetad service leading to the execution of arbitrary code or a Denial of Service.
There is no known workaround at this time.
All Ganglia users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-cluster/ganglia-3.1.1-r2"
