SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that Dovecot incorrectly handled closing inactive SSL/TLS connections. A remote attacker could use this issue to cause Dovecot to stop responding to new connections, resulting in a denial of service.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
