Discussion

Sendmail Queue Processing Data Loss/DoS Vulnerability

Sendmail is a freely available, widely deployed Mail Transport Agent (MTA). It is maintained by the Sendmail Consortium.

Sendmail allows regular users to force processing of the entire mail queue. When running 'sendmail', users can change key configuration variables such as setting the message hop count to a value greater than the limit imposed by sendmail. In doing so, mail in the queue will be dropped when it is processed.

If exploited, an attacker can cause a data loss/denial of service.
