Description Jan Lieskovsky 2012-09-17 08:05:49 EDT
A possibility to bypass file upload size constraint was found in the way the webservice script, called from the filepicker front end of Moodle, a course management system, performed sanitization of 'maxbytes' variable. A remote attacker could issue a specially-crafted request that, when processed could allow an attacker to upload a file even if it was larger than specified constraint.

Not really, only to attach to the Bodhi update. I've already got the builds and the updates done and in the pipe. Might be good for completeness.
