This indicates an attack attempt to exploit a Buffer Overflow vulnerability in SysGauge.
The vulnerability is due to an error when the vulnerable client connected to a malicious server via SMTP. An attacker can exploit this to execute arbitrary code within the context of the system, by tricking an unsuspecting target into connecting to a malicious server.
System Compromise: Remote attackers can gain control of vulnerable systems.
Currently we are unaware of any vendor supplied patch for this issue.
