Prosody is a server for Jabber/XMPP. bug 1084850 / http://xmpp.org/resources/security-notices/uncontrolled-resource-consumption-with-highly-compressed-xmpp-stanzas/ describe a flaw in the way XMPP handles application-layer compression. An attacker could send crafted XMPP stanzas that would cause prosody to use an excessive amount of CPU and memory. This issue has been fixed in version 0.9.4: http://blog.prosody.im/prosody-0-9-4-released/ Upstream fix: http://hg.prosody.im/0.9/rev/b3b1c9da38fb However, based on the patch description, it does not sound like it would resolve the issue where an authenticated user attempts to send malicious XMPP stanzas. Additionally, the Secunia advisories notes mod_compression must be enabled to trigger this issue. It appears, based on looking at prosody.cfg.lua.dist in the Fedora package, that this is enabled by default for Fedora.
