POP3 Request Error: Binary Data

This signature detects binary client-to-server data on a POP3 connection. POP3 connections should not have binary data, as binary attachments are converted to base64 or similar representations. This can indicate a buffer overflow or tunneling attempt.

Extended Description

The presence of binary data in POP3 traffic may indicate an attack. The impact depends on how an affected POP3 server handles the data.
