Synopsis

The remote Red Hat host is missing one or more security updates for dovecot.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:6973 advisory.

 Dovecot is an IMAP server for Linux and other UNIX-like systems, written primarily with security in mind.
 It also contains a small POP3 server, and supports e-mail in either the maildir or mbox format. The SQL drivers and authentication plug-ins are provided as subpackages.

 Security Fix(es):

 * dovecot: using a large number of address headers may trigger a denial of service (CVE-2024-23184)

 * dovecot: very large headers can cause resource exhaustion when parsing message (CVE-2024-23185)
