Descriptions

plugins/mod_compression.lua in (1) Prosody before 0.9.4 and (2) Lightwitch Metronome through 3.4 negotiates stream compression while a session is unauthenticated, which allows remote attackers to cause a denial of service (resource consumption) via compressed XML elements in an XMPP stream, aka an "xmppbomb" attack.

plugins/mod_compression.lua en (1) Prosody anterior a 0.9.4 y (2) Lightwitch Metronome hasta 3.4 negocia compresión de cadena mientras una sesión no está autenticada, lo que permite a atacantes remotos causar una denegación de servicio (consumo de recursos) a través de elementos XML comprimidos en una cadena XMPP, también conocido como un ataque "xmppbomb".

The update for prosody in DSA 2895 caused a regression when a client logins with the compression functionality activated. This update corrects that problem.
