CVE-2018-9846 (opens in a new tab)How to fix?
There is no fixed version for Ubuntu:16.04 roundcube.
NVD Description
Note: Versions mentioned in the description apply only to the upstream roundcube package and not the roundcube package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
In Roundcube from versions 1.2.0 to 1.3.5, with the archive plugin enabled and configured, it's possible to exploit the unsanitized, user-controlled "_uid" parameter (in an archive.php _task=mail&_mbox=INBOX&_action=plugin.move2archive request) to perform an MX (IMAP) injection attack by placing an IMAP command after a %0d%0a sequence. NOTE: this is less easily exploitable in 1.3.4 and later because of a Same Origin Policy protection mechanism.
