Debian: DSA-2895-2 Critical: Prosody Compression DoS Fix

The update for prosody in DSA 2895 caused a regression when a client
logins with the compression functionality activated. This update corrects
that problem. For reference, the original advisory text follows.

A denial-of-service vulnerability has been reported in Prosody, a XMPP
server. If compression is enabled, an attacker might send highly-com-
pressed XML elements (attack known as "zip bomb") over XMPP streams and
consume all the resources of the server.

For the stable distribution (wheezy), this problem has been fixed in
version 0.8.2-4+deb7u2 of prosody.

We recommend that you upgrade your prosody package.
