Debian — Security Information — DSA-4344-1 roundcube

Aidan Marlin discovered that roundcube, a skinnable AJAX based webmail
solution for IMAP servers, is prone to a cross-site scripting
vulnerability in handling invalid style tag content.

For the stable distribution (stretch), this problem has been fixed in
version 1.2.3+dfsg.1-4+deb9u3.

We recommend that you upgrade your roundcube packages.
