Detail

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.
