Importante Aos Usuários Do Moodle

Hello registered Moodle Admins!

(This email is going out to over 86,000 registered Moodle admins. You

are receiving this email because you asked for Moodle security news

when you registered a Moodle site. If you don't want these emails

then see the very end of this email for info about unsubscribing.

Replies to this email will not be read.)

I'm writing today to let you know that Moodle 2.3.3, 2.2.6 and 2.1.9

are available via the usual open download channels

(http://download.moodle.org, CVS or Git).

Note that we will no longer be providing updates via a CVS mirror

from Jan 1, 2013. (https://moodle.org/mod/forum/discuss.php?d=215489)

Note that the 2.1 and 1.9 branches are now supported for security

fixes only. Also note that no release has been made in the 1.9 branch

but there have been serious security issues fixed in this branch.

The full release notes are here:

* http://docs.moodle.org/dev/Moodle_2.3.3_release_notes

* http://docs.moodle.org/dev/Moodle_2.2.6_release_notes

* http://docs.moodle.org/dev/Moodle_2.1.9_release_notes

SECURITY ISSUES

As well as a long list of bug fixes, performance improvements and

polishing, there are 7 security issues you should be aware of.

Details of these security issues are listed below.

As a registered Moodle admin we are giving you advance notice of these

issues so you have some time to fix them before we publish them more

widely on http://moodle.org/security in one week.

To avoid leaving your site vulnerable we highly recommend you upgrade

your sites to the latest Moodle version as soon as you can.

If you cannot upgrade then please check the following list carefully

and patch your own system or switch off those features.

Thanks, as always, to EVERYONE involved in reporting and fixing security

issues. It really is a team effort and one with more and more people

involved all the time.

Cheers and thanks for using Moodle!
