GKrellM GKrellWeather Plugin Local Stack Based Buffer Overflow Vulnerability

The GKrellWeather plugin for GKrellM is prone to a local stack-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized buffer.

An attacker can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in denial-of-service conditions.
