roundcube - security update

Roundcube, a webmail solution for IMAP servers, was susceptible to
cross-site-scripting (XSS) vulnerabilities when handling SVG images.
When right-clicking on the download link of an attached image, it was
possible that embedded Javascript could be executed in a separate Tab.

The update disables displaying of SVG images in e-mails and TABS.
Downloading attachments is still possible. This security update also
mitigates against other ways to exploit this issue in SVG images.
(CVE-2016-4068)

For Debian 7 Wheezy, these problems have been fixed in version
0.7.2-9+deb7u3.

We recommend that you upgrade your roundcube packages.
