Dear Roundcube users

We just published updates to both stable versions 1.0 and 1.1 delivering important bug fixes one of which seals a potential path traversal vulnerability [1] recently reported by High-Tech Bridge Security Research Lab. Although the vulnerability is not fully disclosed yet, the attack scenario requires an active Roundcube account as well as write privileges on the same host Roundcube is served from (without open_basedir protection).

A second security improvement adds some measures against brute-force attacks. See the full changelog here: http://trac.roundcube.net/wiki/Changelog#RELEASE1.1.4

Both versions are considered stable and we recommend to update all productive installations of Roundcube with either of these versions. Download them from https://roundcube.net/download

If you prefer to patch your installation for the path traversal vulnerability only, we also published patches on our download mirrors for versions 1.0 [2] and 1.1 [3].

As usual, don't forget to backup your data before updating!

Thanks for all your support and happy new year!

Thomas
