Debian Security Advisory DSA-1470-1 security@debian.org
http://www.debian.org/security/ Moritz Muehlenhoff

- ------------------------------------------------------------------------

Package : horde3
Vulnerability : missing input sanitising
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2007-6018

Ulf Harnhammer discovered that the HTML filter of the Horde web
application framework performed insufficient input sanitising, which
may lead to the deletion of emails if a user is tricked into viewing
a malformed email inside the Imp client.

This update also provides backported bugfixes to the cross-site
scripting filter and the user management API from the latest Horde
release 3.1.6.

For the stable distribution (etch), this problem has been fixed in
version 3.1.3-4etch2.

The old stable distribution (sarge) is not affected. An update to
Etch is recommended, though.

We recommend that you upgrade your horde3 package.

Upgrade instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
