Debian Security Advisory DSA-2033-1 security@debian.org http://www.debian.org/security/ Sebastien Delafond April 15th, 2010 http://www.debian.org/security/faq


Package : ejabberd Vulnerability : heap overflow Problem type : remote Debian-specific: no CVE Id : CVE-2010-0305 Debian Bug : 568383

It was discovered that in ejabberd, a distributed XMPP/Jabber server written in Erlang, a problem in ejabberd_c2s.erl allows remote authenticated users to cause a denial of service by sending a large number of c2s (client2server) messages; that triggers an overload of the queue, which in turn causes a crash of the ejabberd daemon.

For the stable distribution (lenny), this problem has been fixed in version 2.0.1-6+lenny2.

For the testing distribution (squeeze), this problem has been fixed in version 2.1.2-2.

For the testing distribution (sid), this problem has been fixed in version 2.1.2-2.

We recommend that you upgrade your ejabberd packages.
