Patch applied from Debian #360395. - The embedded version of lib/adodb/adodb-pager.inc.php is susceptible to XSS as described in CVE-2006-0806. Patch applied from Debian #360396. * References: http://bugs.debian.org/360395, CVE-2006-0410; http://bugs.debian.org/360396, CVE-2006-0806. * debian/: - postinst: Handle the upgrade path from any previous packaging revision in Breezy and Dapper that depends on apache2 but mistakenly uses apache in the debconf template. - templates: Use apache2 by default since, well, that's what the dependency prefers. Now Moodle actually installs. (Closes: Malone #5501, Malone #47812).
