Debian Security Advisory DSA-2249-1 firstname.lastname@example.org http://www.debian.org/security/ Nico Golde March 31, 2011 http://www.debian.org/security/faq
Package : jabberd14 Vulnerability : denial of service Problem type : remote Debian-specific: no CVE ID : CVE-2011-1754
Wouter Coekaerts discovered that jabberd14, an instant messaging server using the Jabber/XMPP protocol, 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.
The oldstable distribution (lenny), does not contain jabberd14.
For the stable distribution (squeeze), this problem has been fixed in version 18.104.22.168-5+squeeze1.
For the testing distribution (wheezy), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in version 22.214.171.124-5.1
We recommend that you upgrade your jabberd14 packages.
