[Roundcube Announce] Security updates 1.4.4, 1.3.11 and 1.2.10 released

[Thomas Bruederli]

Dear subscribers

We just published service and security updates to the stable version 1.4
and the LTS versions 1.3 and 1.2 of Roundcube Webmail. They contain four
fixes for recently reported security vulnerabilities as well a number of
general improvements from our issue tracker.

Security fixes:
- Cross-Site Scripting (XSS) via malicious HTML content
- CSRF attack can cause an authenticated user to be logged out
- Remote code execution via crafted config options
- Path traversal vulnerability allowing local file inclusion via crafted
‘plugins’ option

The latter two vulnerabilities are classified minor because they only
affect Roundcube installations with public access to the Roundcube
installer. That’s generally a high-risk situation and is expected to be
rare or practically non-existent in productive Roundcube deployments.
However, the fixes are done in core in order to also prevent from future
and yet unknown attack vectors.

See the full changelogs in the release notes on the Github download pages
[1].

We strongly recommend to update all productive installations of Roundcube
with this new versions.

Best,
Thomas & Alec
