Nessus complains about sendmail

Hi list, today I ran Nessus against our internet server. This server also provides mail services with Sendmail. RPM -q shows Sendmail 8.11.2-4. The system is SuSE 7.1. Nessus complained that there might be a buffer overflow if the 'MAIL FROM' command string becomes too long. As I cannot find anything about this issue in Sendmail's known bugs list and as the running Sendmail did not crash, I wonder if this is some kind of false alarm or a real issue. If it is real, will there be an update? Bye, Jürgen
