-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Package        : mosquitto
Version        : 1.3.4-2+deb8u4
CVE ID         : CVE-2017-7655 CVE-2018-12550 CVE-2018-12551
                 CVE-2019-11779


Several issues have been found in mosquitto, a MQTT version 3.1/3.1.1 compatible message broker.

CVE-2017-7655

     A Null dereference vulnerability in the Mosquitto library could
     lead to crashes for those applications using the library.


CVE-2018-12550

     An ACL file with no statements was treated as having a default
     allow policy. The new behaviour of an empty ACL file is a default
     policy of access denied.
     (this is in compliance with all newer releases)


CVE-2018-12551

     Malformed authentication data in the password file could allow
     clients to circumvent authentication and get access to the broker.


CVE-2019-11779

     Fix for processing a crafted SUBSCRIBE packet containing a topic
     that consists of approximately 65400 or more '/' characters.
     (setting TOPIC_HIERARCHY_LIMIT to 200)


For Debian 8 "Jessie", these problems have been fixed in version
1.3.4-2+deb8u4.

We recommend that you upgrade your mosquitto packages.
