Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DSA-2248-1)
Summary:	The remote host is missing an update for the Debian 'ejabberd' package(s) announced via the DSA-2248-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'ejabberd' package(s) announced via the DSA-2248-1 advisory. Vulnerability Insight: 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. Affected Software/OS: 'ejabberd' package(s) on Debian 5, Debian 6. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
