This allows an attacker to perform denial of service attacks against the service by sending specially crafted XML data to it. For the oldstable distribution (lenny), this problem has been fixed in version 7.37-8+lenny1. For the stable distribution (squeeze), this problem has been fixed in version 7.83-2squeeze2. For the testing (wheezy) and unstable(sid) distributions, this problem will be fixed soon. We recommend that you upgrade your citadel packages.
