"Upstream announcement :

**Version 1.3.6**

This is a security update to the stable version 1.3. It primarily
fixes a recently discovered IMAP command injection vulnerability
caused by insufficient input validation within the archive plugin.
Details about the vulnerability are published under CVE-2018-9846.

Additionally, we back-ported some minor fixes from the master branch
which improve PHP 7.2 compatibility as well as PGP signing and key
handling for those who use the Enigma plugin. See the complete
changelog below.

We strongly recommend to update all productive installations of
Roundcube. Please do backup your data before updating!

**CHANGELOG**

  - Fix parsing date strings (e.g. from a Date: mail header)
    with comments (#6216)

  - Fix PHP 7.2: count(): Parameter must be an array in
    enchant-based spellchecker (#6234)

  - Fix possible IMAP command injection and type juggling
    vulnerabilities (#6229)

  - Enigma: Fix key selection for signing

  - Enigma: Enable keypair generation on Internet Explorer
    11

  - Fix check_request() bypass in places using get_uids()
    [CVE-2018-9846] (#6238)

  - Fix bug where usernames without domain part could be
    malformed or converted to lower-case on logon (#6224)

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
