"CVE-2017-7651 fix to avoid extraordinary memory consumption by crafted
CONNECT packet from unauthenticated client

CVE-2017-7652 in case all sockets/file descriptors are exhausted, this
is a fix to avoid default config values after reloading configuration
by SIGHUP signal

For Debian 8 'Jessie', these problems have been fixed in version
1.3.4-2+deb8u2.

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
introducing additional issues."
