Re: SQL injection - moodle

["scsantos@unigranrio com br" <scsantos () unigranrio com br>]

A security vulnerability was recently discovered in all versions of
Moodle 1.6 and later that allows SQL injection. A quick one-line fix has
already been added to CVS to patch this problem for 1.6.x and 1.7 versions.

Update your servers using CVS as soon as possible, or edit the file
blog/index.php in your copy manually as described here:

    http://cvs.moodle.com/blog/index.php?r1=1.18.2.2&r2=1.18.2.3
