Debian Security Advisory DSA-2895-2 security@debian.org
http://www.debian.org/security/ Luciano Bello
April 21, 2014 http://www.debian.org/security/faq

Package : prosody
CVE ID : CVE-2014-2744 CVE-2014-2745
Debian Bug : 743836
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.
