CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Horde Application Framework 3.x

DESCRIPTION:
Daniel Schreckling has reported some vulnerabilities in Horde, which
can be exploited by malicious people to conduct script insertion
attacks.

The vulnerabilities are caused due to input validation errors in the
gzip/tar and css MIME viewers. This can e.g. be exploited to inject
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site when a malicious mail
with a specially crafted inline attachment is viewed with the IMP
webmail client.

The vulnerabilities have been reported in versions prior to 3.0.7.

SOLUTION:
Update to version 3.0.7:
ftp://ftp.horde.org/pub/horde/horde-3.0.7.tar.gz

Apply patch for version 3.0.6:
ftp://ftp.horde.org/pub/horde/patches/patch-horde-3.0.6-3.0.7.gz
