Synopsis

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

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:6465 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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL dovecot package based on the guidance in RHSA-2024:6465.
