The remote host is missing an update to ganglia-monitor-core announced via advisory DSA 1710-1.

Spike Spiegel discovered a stack-based buffer overflow in gmetad, the meta-daemon for the ganglia cluster monitoring toolkit, which could be triggered via a request with long path names and might enable arbitrary code execution. For the stable distribution (etch), this problem has been fixed in version 2.5.7-3.1etch1. For the unstable distribution (sid) this problem has been fixed in version 2.5.7-5. For the testing distribution (lenny), this problem will be fixed soon. We recommend that you upgrade your ganglia-monitor-core packages.
