Update Information:
Prosody 0.11.9 ============== This release addresses a number of important
security issues that affect most deployments of Prosody. Full details are
available in a separate security advisory. Upstream recommends that all
deployments upgrade or apply the mitigations described in the advisory:
https://prosody.im/security/advisory_20210512/ Note: Upstream updated the
default config file. DNF or RPM will create a
`/etc/prosody/prosody.cfg.lua.rpmnew` file, so make sure you update your
existing `/etc/prosody/prosody.cfg.lua` to enable mod_limits after the upgrade.
Security -------- * mod_limits, prosody.cfg.lua: Enable rate limits by
default * certmanager: Disable renegotiation by default * mod_proxy65:
Restrict access to local c2s connections by default * util.startup: Set more
aggressive defaults for GC * mod_c2s, mod_s2s, mod_component, mod_bosh,
mod_websockets: Set default stanza size limits *
mod_auth_internal_{plain,hashed}: Use constant-time string comparison for
secrets * mod_dialback: Remove dialback-without-dialback feature *
mod_dialback: Use constant-time comparison with hmac Minor changes
------------- * util.hashes: Add constant-time string comparison (binding to
`CRYPTO_memcmp`) * mod_c2s: Don���t throw errors in async code when connections
are gone * mod_c2s: Fix traceback in session close when conn is nil *
core.certmanager: Improve detection of LuaSec/OpenSSL capabilities *
mod_saslauth: Use a defined SASL error * MUC: Add support for advertising
muc#roomconfig_allowinvites in room disco#info * mod_saslauth: Don���t throw
errors in async code when connections are gone * mod_pep: Advertise base
pubsub feature (fixes #1632: mod_pep missing pubsub feature in disco) *
prosodyctl check config: Add `gc` to list of global options * prosodyctl
about: Report libexpat version if known * util.xmppstream: Add API to
dynamically configure the stanza size limit for a stream * util.set: Add
`is_set()` to test if an object is a set * mod_http: Skip IP resolution in
non-proxied case * mod_c2s: Log about missing conn on async state changes *
