The Horde Team is pleased to announce the final release of the Horde Groupware
Webmail Edition version 1.1.6.

This is a major security release that fixes a vulnerability in the form
library that allows overwriting of arbitrary local files with the permissions
of the web server user. It also fixes two XSS vulnerabilities in the
preference system and the MIME viewer library. The local file vulnerability
can not be exploited with any application bundled with Horde Groupware Webmail
Edition 1.1.x. All users are encouraged to upgrade to this release.

Thanks to Stefan Esser from SektionEins for finding the local file issue in a
code audit, and Martin Geisler and David Wharton for finding the XSS issues.

Horde Groupware Webmail Edition is a free, enterprise ready, browser based
communication suite. Users can read, send and organize email messages with
three different webmail interfaces and manage and share calendars, contacts,
tasks and notes with the standards compliant components from the Horde
