Moodle 1.9.10 is released and all Administrators are urged to upgrade to the latest version in order to safeguard their site against fixed security flaws. For full information and release notes visit http://docs.moodle.org/en/Moodle_1.9.10_release_notes.
According to the release notes over 100 bugs/issues were corrected in the code. You may download the upgrade files from http://download.moodle.org/.
All the details have already been published (it was not possible to
give Moodle admins advance warning this time due to constraints from
external development teams we coordinated with), so please update your
sites as soon as possible to remove any risk of them being attacked
using these known vulnerabilities.
Thanks as always to everyone involved in reporting and fixing security
issues for all their hard work.
Cheers and thanks for using Moodle! (Moodle 2.0 is very close now!)
