When nbsmtp is executed in debug mode, server messages will be printed to stdout and logged via syslog. Syslog is used insecurely and user-supplied format characters are directly fed to the syslog function, which results in a format string vulnerability.
Under some circumstances, an SMTP server may be able to abuse this vulnerability in order to alter the nbsmtp process and execute malicious code.
