Package : dovecot CVE ID : CVE-2024-23184 CVE-2024-23185

Two vulnerabilities have been discovered in the IMAP implementation of the Dovecot mail server: Excessive numbers of address headers or very large headers can result in high CPU usage, leading to denial of service.

For the stable distribution (bookworm), these problems have been fixed in version 1:2.3.19.1+dfsg1-2.1+deb12u1.

We recommend that you upgrade your dovecot packages.
