extplorer - security update

Multiple cross-site scripting (XSS) vulnerabilities have been discovered
in extplorer, a web file explorer and manager using Ext JS.
A remote attacker can inject arbitrary web script or HTML code via a
crafted string in the URL to application.js.php, admin.php, copy_move.php,
functions.php, header.php and upload.php.

For the oldstable distribution (squeeze), this problem has been fixed in
version 2.1.0b6+dfsg.2-1+squeeze2.

For the stable distribution (wheezy), this problem has been fixed in
version 2.1.0b6+dfsg.3-4+deb7u1.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your extplorer packages.
