Debian: Security update for Moodle

Several security issues have been fixed in Moodle, a course management system for online learning. Rossiani Wijaya discovered an information leak in mod/forum/user.php MNET authentication didn’t prevent a user using “Login As” from jumping to a remove MNET SSO. Darragh Enright discovered that the change password form was send in over plain HTTP even if httpslogin was set to “true”.

David Michael Evans and German Sanchez Gances discovered CRLF injection/HTTP response splitting vulnerabilities in the Calendar module. Stephen Mc Guiness discovered empty passwords could be entered in some circumstances. Patrick McNeill that IP address restrictions could be bypassed in MNET.

Simon Coggins discovered that additional information could be injected into mail headers. John Ehringer discovered that email adresses were insufficiently validated. Rajesh Taneja discovered that cookie encryption used a fixed key.

Eloy Lafuente discovered that profile images were insufficiently protected. A new configuration option “forceloginforprofileimages” was introduced for that.

Updated packages are available from security.debian.org.
