CVE-2011-4581: Infoleak

First published: Wed Dec 07 2011(Updated: )

A number of flaws have been fixed in new upstream Moodle 2.1.3 [1], 2.0.6 [2], and 1.9.15 [3] releases. These do not have CVEs assigned (request pending), and since Fedora/EPEL will rebase to the latest versions of each branch, I'm summarizing them all here rather than creating a number of separate bugs.
