mosquitto (1.5.7-1) unstable; urgency=medium
* New upstream release.
* Remove fix-step3.patch, fixed upstream.
* bug-1162.patch: fix bug with clients being disconnected in some situations
when ACLs are in use.

mosquitto (1.5.6-1) unstable; urgency=medium
* SECURITY UPDATE: If Mosquitto is configured to use a password file for
authentication, any malformed data in the password file will be treated as
valid. This typically means that the malformed data becomes a username and
no password. If this occurs, clients can circumvent authentication and get
access to the broker by using the malformed username. In particular, a blank
line will be treated as a valid empty username. Other security measures are
unaffected. Users who have only used the mosquitto_passwd utility to create
and modify their password files are unaffected by this vulnerability.
- debian/patches/mosquitto-1.4.x-cve-2018-12551.patch: this fix introduces
more stringent parsing tests on the password file data.
- CVE-2018-12551
* SECURITY UPDATE: If an ACL file is empty, or has only blank lines or
comments, then mosquitto treats the ACL file as not being defined, which
means that no topic access is denied. Although denying access to all
topics is not a useful configuration, this behaviour is unexpected and
could lead to access being incorrectly granted in some circumstances.
- debian/patches/mosquitto-1.4.x-cve-2018-12550.patch: this fix ensures
that if an ACL file is defined but no rules are defined, then access will
be denied.
- CVE-2018-12550
* SECURITY UPDATE: If a client publishes a retained message to a topic that
they have access to, and then their access to that topic is revoked, the
retained message will still be delivered to future subscribers. This
behaviour may be undesirable in some applications, so a configuration
option `check_retain_source` has been introduced to enforce checking of
the retained message source on publish.
- debian/patches/mosquitto-1.4.8-cve-2018-12546.patch: this patch stores
the originator of the retained message, so security checking can be
carried out before re-publishing. The complexity of the patch is due to
the need to save this information across broker restarts.
- CVE-2018-12546
* New upstream release.
* Bump standards version to 4.3.0, no changes needed.
* fix-step3.patch: fix compilation error.

mosquitto (1.5.5-1.1) unstable; urgency=medium
* Non-maintainer upload.
* Only chown mosquitto.log if it exists. (Closes: #916558)
2018-12-11 - Roger A. Light <>
mosquitto (1.5.5-1) unstable; urgency=medium
* SECURITY UPDATE: If the option `per_listener_settings` was set to true,
and the default listener was in use, and the default listener specified an
`acl_file`, then the acl file was being ignored. This affects version 1.5
to 1.5.4 inclusive.
* New upstream release.
2018-11-25 - Roger A. Light <>
mosquitto (1.5.4-2) unstable; urgency=medium
* debian/patches/914525.patch : Use pkg-config to get systemd libs
(Closes: #914525)
- This is needed to allow compilation on non-Linux systems.
* Fix FTCBFS: Let dh_auto_build pass cross tools to make. Thanks to Helmut
Grohne. (Closes: #914593)
* Ensure log files are owned by mosquitto. (Closes: #877346)
