A flaw was found in dovecot. A remote attacker can exploit the Internet Message Access Protocol (IMAP) SETACL command to inject "anyone" permissions into a user's dovecot-acl file, even when the imap_acl_allow_anyone setting is disabled. This vulnerability allows an attacker to spam folders to all users, leading to a denial of service by disrupting normal email service. No unauthorized access to user data is gained.
Меры по смягчению последствий
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.
