Fedora Update Notification
2015-04-21 13:39:48

Name : prosody
Product : Fedora 20
Version : 0.9.8
Release : 1.fc20
Summary : Flexible communications server for Jabber/XMPP
Description :
Prosody is a flexible communications server for Jabber/XMPP written in Lua.
It aims to be easy to use, and light on resources. For developers it aims
to be easy to extend and give a flexible system on which to rapidly develop
added functionality, or prototype new protocols.

Update Information:

Prosody 0.9.8

A summary of changes in this release:


* Ensure only valid UTF-8 is passed to libidn. It was found (CVE-2015-2059) that libidn can read beyond the boundaries of the provided buffer when an input string contains invalid UTF-8 sequences.

Systems where Prosody is compiled to use libICU are not affected by this issue.


* DNS: Fix traceback caused when DNS server IP is unroutable (issue 473)
* HTTP client: More robust handling of chunked encoding across packet boundaries
* Stanza router: Fix handling of ‘error’ <iq>’s with multiple children


* c2s: Fix error reply when clients try to bind multiple resources on the same stream (issue 484)
* s2s: Ensure to/from attributes are always present on stream headers, even if empty (issue 468)
* Build scripts: Add –libdir option to ./configure to simplify building on some platforms
* Fix traceback in datamanager when used outside of Prosody (e.g. in some migration tools)
* mod_admin_telnet: Fix potential traceback in server:memory() command (issue 471)
* HTTP server: Improved debug logging

Prosody 0.9.7

A summary of changes in this release:

* util.stanza: Don’t XML-escape whitespace
* prosodyctl: Fix traceback in ‘about’ command with LuaRocks 2.2.0

Prosody 0.9.6

Note: This release disables SSLv3 by default, which has been shown to be insecure when used by clients. Clients that only support SSLv3 will no longer be able to connect. There are not many of these nowadays, but they exist.

A summary of changes in this release:

* certmanager, net.http: Disable SSLv3 by default
* net.http.parser: Support status code 101 and allow handling of the received data by plugins
* util.filters: Ignore filters being added twice (fixes issues on removal, i.e. when some plugins are reloaded/unloaded)
* mod_s2s: Close offending s2s streams missing an ‘id’ attribute with a stream error instead of throwing an unhandled error
* Networking API: Add ‘ondetach’ callback for listener objects, to prevent leaks when connections have their listener changed
* core.stanza_router: Stricter validation of stanzas
* mod_admin_adhoc: Mark ‘accountjids’ field as required in ‘end user sessions’ command (thanks Lloyd)
* mod_admin_adhoc: Add required to field in user deletion form too
* net.dns: Avoid duplicate cache entries
* util.stanza: Escape newlines and tabs (
) when serializing stanzas.
* util/dataforms: Make sure we iterate over field tags only
* mod_s2s: Capitalize log message
* mod_pubsub: Fix error type of ‘forbidden’ (change from ‘cancel’ to ‘auth’)

Prosody 0.9.5

A summary of changes in this release:

* C2S: Fix traceback if a client opens a stream to component, which could cause a crash in combination with some versions of LuaEvent
* C2S, S2S: Log received invalid stream headers
* S2S: Fix case where stream headers were sometimes sent twice
* DNS: Ensure all pending requests get notified of a timeout when looking up a record
* DNS: Fix duplicated cache insertions by limiting outstanding queries per name to one
* xmppstream: Disable LuaExpat’s buffering
* xmppstream: Disable CharacterData merging after stream restarts
* xmppstream: Pass invalid stream headers to error handling
* Privacy lists: Correctly sort privacy list rules by order
* prosody: Check dependencies later in the startup sequence
* Config: Delay importing LuaFileSystem until needed by an Include line
* Config: Normalize VirtualHost and Component names
* prosodyctl: Normalize JIDs for adduser/passwd/deluser
* POSIX: Fix error reporting from disk space allocation
* POSIX: Verify that ‘pidfile’ is a string, show friendly error otherwise
* Dependency checking: Check that prosody is running under Lua 5.1. We don’t currently support any other versions. (LuaJIT identifies as 5.1)
* Compliance: Reset stream ID when resetting stream
* Compression: Log compression setup errors
* Console: Fix commands for adding and replacing name servers
* Console MUC commands: Fix error when a non-existent host is entered
* Filters: Prevent filters from being added twice
* Network: Transfer all available data between linked sockets
* dataforms: Add support for XEP-0221: Data Forms Media Element

Prosody 0.9.4

A summary of changes in this release:

* Compression: Disallow compression on unauthenticated streams
* Core: Limit default read size and maximum stanza size
* Core: Enable SASL EXTERNAL by default for component s2s
* S2S: Warn if `s2s_secure_auth` and `s2s_require_encryption` have been set in conflicting ways
* S2S: Warn if no local network addresses were found, preventing successful s2s
* MUC: Fix traceback when a non-occupant tried to change an occupant’s role
* MUC: API: Fire an event when temporary rooms are destroyed after the last person leaves
* Telnet: Fixed traceback when listing users
* Telnet: Apply normalization to JIDs in user management commands
* HTTP: Fix directory detection in file server on Windows
* Plugins: Fix paths on Windows
* MOTD: Don’t strip blank lines from the message provided in the config
* prosodyctl: Better error reporting when generating certificates
* Makefile: Improve FreeBSD compatibility
* Multiple fixes to our migration tools, and support for importing MUCs from ejabberd

Prosody 0.9.3

A summary of changes in this release:

* A config file passed as command line argument is no longer forgotten when config is reloaded
* MUC: Allow admins to always bypass restrict_room_creation
* Strip trailing ‘.’ when normalizing hostnames
* HTTP: Prevent silent connection failures
* Components: Alow easier overriding of component authentication by plugins
* Components: Enable TCP keepalives
* Migrator: Better error reporting and improved robustness
* S2S: Include IP in log messages, if hostname is unavailable
* TLS: Log error when initialization fails

Prosody 0.9.2

Note: If you are upgrading from 0.8.x or earlier, please read the 0.9.0 upgrade notes at!

A summary of changes in this release:

* Debian/Ubuntu packages fixed to always generate per-system certs
* TLS: Improved cipher string, and use Prosody’s preferred ciphers instead of the client’s
* MUC: Fix for Spark clients not displaying room lists
