Descriptions

Prosody before 0.9.4 does not properly restrict the processing of compressed XML elements, which allows remote attackers to cause a denial of service (resource consumption) via a crafted XMPP stream, aka an "xmppbomb" attack, related to core/portmanager.lua and util/xmppstream.lua.

Prosody anterior a 0.9.4 no restringe debidamente el procesamiento de elementos XML comprimidos, lo que permite a atacantes remotos causar una denegación de servicio (consumo de recursos) a través de una cadena XMPP manipulada, también conocido como una ataque "xmppbomb", relacionado con core/portmanager.lua y util/xmppstream.lua.

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