CVE-2026-40017
A flaw was found in Dovecot. A remote attacker who can send mail to a user can craft a message header designed to cause collisions in an internal hash table. This manipulation forces the IMAP THREAD command to consume excessive CPU resources, leading to degradation or a complete denial of service...
CVE-2026-40014
A flaw was found in Dovecot. A remote attacker, by sending a specially crafted email message header to a user, can cause the Internet Message Access Protocol IMAP THREAD command to consume excessive CPU resources. When a mail client processes this message, it can lead to degradation or a denial o...
