POP3: Buffer Overflow Username
This protocol anomaly triggers when it detects a POP3 USER command argument that is too long. This can indicate a buffer overflow attempt.
Extended Description
Receiving such a message could indicate a software misconfiguration or an attacker is attempting to cause a buffer overflow. The impact depends on how the POP3 server handles those packets.
