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.
