Summary

SMTP command injection in body

Details

Affected versions of lettre allowed SMTP command injection through an attacker's controlled message body. The module for escaping lines starting with a period wouldn't catch a period that was placed after a double CRLF sequence, allowing the attacker to end the current message and write arbitrary SMTP commands after it.

The flaw is fixed by correctly handling consecutive CRLF sequences.
