Description Jan Lieskovsky 2013-03-25 13:39:57 UTC

A cross-site scripting (XSS) flaw was found in the way File picker (enables files to be selected and displayed in Moodle) of Moodle, a course management system, performed file content sanitization prior depiction. A remote attacker could provide a specially-crafted file that, when opened in Moodle's File picker add-on would lead to arbitrary HTML or web script execution (in the context of the Moodle user's session).

Comment 1 Jan Lieskovsky 2013-03-25 13:57:03 UTC

This issue affects the version of the moodle package, as shipped with Fedora release of 18. Please schedule an update.

--

This issue (probably [*]) affects the versions of the moodle package, as shipped with Fedora release of 17 and Fedora EPEL-6.

[*] Probably because by comparing particular upstream patch with underlying source code provided patch doesn't seem to be (directly) applicable. But those versions are listed as affected in advisory [1] too.

--

This issue did NOT affect the version of the moodle package, as shipped with Fedora EPEL-5.
