Title: Ganglia gmetad 'process_path()' Remote Stack Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
Ganglia is a distributed monitoring system for high-performance computers.
The application is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. This issue affects the 'process_path()' function of the 'gmetad' component. Specifically the overflow occurs when the software passes data to a 256-byte fixed-size buffer and later uses it in a 'strncpy()' call without checking the length of the data. If the data is large enough, the function call will write data to an arbitrary location in memory, causing memory to become corrupted.
Attackers can leverage this issue to execute arbitrary code in the context of the application. Successful exploits will compromise the application and the underlying computer. Failed attacks will cause denial-of-service conditions.
