 Vulnerabilities were discovered in dovecot, an POP3/IMAP server, which could lead to Denial of Service.

 CVE-2024-23184

 Having a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive.

 CVE-2024-23185

 Very large headers can cause resource exhaustion when parsing message.

 For Debian 11 bullseye, these problems have been fixed in version 1:2.3.13+dfsg1-2+deb11u2.

 We recommend that you upgrade your dovecot packages.
