ID:	200911-01

Synopsis

Multiple vulnerabilities in the Horde Application Framework can allow for arbitrary files to be overwritten and cross-site scripting attacks.

Background

Horde is a web application framework written in PHP.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)

www-apps/horde-webmail	< 1.2.4	>= 1.2.4	All supported architectures
www-apps/horde-groupware	< 1.2.4	>= 1.2.4	All supported architectures

Description

Multiple vulnerabilities have been discovered in Horde:

Stefan Esser of Sektion1 reported an error within the form library when handling image form fields (CVE-2009-3236).
Martin Geisler and David Wharton reported that an error exists in the MIME viewer library when viewing unknown text parts and the preferences system in services/prefs.php when handling number preferences (CVE-2009-3237).

Impact

A remote authenticated attacker could exploit these vulnerabilities to overwrite arbitrary files on the server, provided that the user has write permissions. A remote authenticated attacker could conduct Cross-Site Scripting attacks.

Workaround

There is no known workaround at this time.
