Title: Avirt Mail 'Mail From:' and 'Rcpt to:' DoS Vulnerability
Severity: MODERATE
Description:
Due to insufficient bounds checking in the code that handles the fields 'MAIL FROM:' and 'RCPT TO:', it is possible to remotely crash Avirt Mail.
Entering over 272 characters into the 'RCPT TO:' field will crash the application upon termination of the session and no further connections can be initiated until Avirt Mail is restarted. This is also the case with the 'MAIL FROM' field with the exception that over 556 characters must be entered.
Affected Products:
- Avirt Mail 4.0.0
- Avirt Mail 4.2.0
