Debian Security Advisory DSA-2248-1 firstname.lastname@example.org http://www.debian.org/security/ Nico Golde March 31, 2011 http://www.debian.org/security/faq
Package : ejabberd Vulnerability : denial of service Problem type : remote Debian-specific: no CVE ID : CVE-2011-1753
Wouter Coekaerts discovered that ejabberd, a distributed XMPP/Jabber server written in Erlang, is vulnerable to the so-called "billion laughs" attack because it does not prevent entity expansion on received data. 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 2.0.1-6+lenny3.
For the stable distribution (squeeze), this problem has been fixed in version 2.1.5-3+squeeze1.
For the testing distribution (wheezy), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in version 2.1.6-2.1.
We recommend that you upgrade your ejabberd packages.
