A flaw was found in Dovecot. Processing a large number of address headers (From, To, Cc, Bcc, etc) can be excessively CPU intensive. This flaw allows a remote attacker to trigger a denial of service.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
