"CVE-2017-7653

As invalid UTF-8 strings are not correctly checked, an attacker could
cause a denial of service to other clients by disconnecting them from
the broker with special crafted topics.

CVE-2017-7654

Due to a memory leak unauthenticated clients can send special crafted
CONNECT packets which could cause a denial of service in the broker.

CVE-2017-9868

Due to wrong file permissions local users could obtain topic
information from the mosquitto database.

For Debian 8 'Jessie', these problems have been fixed in version
1.3.4-2+deb8u3.

We recommend that you upgrade your mosquitto packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
