[SECURITY] [DLA 961-1] mosquitto security update
-----BEGIN PGP SIGNED MESSAGE-----
Package : mosquitto
Version : 0.15-2+deb7u1
CVE ID : CVE-2017-7650
Debian Bug :
CVE-2017-7650: Pattern based ACLs can be bypassed by clients that set their username/client id to ‘#’ or ‘+’.
This allows locally or remotely connected clients to access MQTT topics that they do have the rights to.
The same issue may be present in third party authentication/access control plugins for Mosquitto.
The vulnerability only comes into effect where pattern based ACLs are in use,
or potentially where third party plugins are in use.
For Debian 7 "Wheezy", these problems have been fixed in version
We recommend that you upgrade your mosquitto packages.
