The remote Red Hat host is missing one or more security updates.
Updated dovecot packages that fix one security issue are now available
for Red Hat Enterprise Linux 6 and 7.
The Red Hat Security Response Team has rated this update as having
Moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
Dovecot is an IMAP server, written with security primarily in mind,
for Linux and other UNIX-like systems. It also contains a small POP3
server. It supports mail in both the maildir or mbox format. The SQL
drivers and authentication plug-ins are provided as subpackages.
It was discovered that Dovecot did not properly discard connections
trapped in the SSL/TLS handshake phase. A remote attacker could use
this flaw to cause a denial of service on an IMAP/POP3 server by
exhausting the pool of available connections and preventing further,
legitimate connections to the IMAP/POP3 server to be made.
All dovecot users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After
installing the updated packages, the dovecot service will be restarted
