    Several remote vulnerabilities have been discovered in Moodle, a
    course management system.  The Common Vulnerabilities and Exposures
    project identifies the following problems:
    
    CVE-2010-1613
    	Moodle does not enable the "Regenerate session id during
    	login" setting by default, which makes it easier for remote
    	attackers to conduct session fixation attacks.
    
    CVE-2010-1614
    	Multiple cross-site scripting (XSS) vulnerabilities allow
    	remote attackers to inject arbitrary web script or HTML via
    	vectors related to (1) the Login-As feature or (2) when the
    	global search feature is enabled, unspecified global search
    	forms in the Global Search Engine.
    
    CVE-2010-1615
    	Multiple SQL injection vulnerabilities allow remote attackers
    	to execute arbitrary SQL commands via vectors related to (1)
    	the add_to_log function in mod/wiki/view.php in the wiki
    	module, or (2) "data validation in some forms elements"
    	related to lib/form/selectgroups.php.
    
    CVE-2010-1616
    	Moodle can create new roles when restoring a course, which
    	allows teachers to create new accounts even if they do not
    	have the moodle/user:create capability.
    
    CVE-2010-1617
    	user/view.php does not properly check a role, which allows
    	remote authenticated users to obtain the full names of other
    	users via the course profile page.
    
    CVE-2010-1618
    	A Cross-site scripting (XSS) vulnerability in the phpCAS
    	client library allows remote attackers to inject arbitrary web
    	script or HTML via a crafted URL, which is not properly
    	handled in an error message.
    
    CVE-2010-1619
    	A Cross-site scripting (XSS) vulnerability in the
    	fix_non_standard_entities function in the KSES HTML text
    	cleaning library (weblib.php) allows remote attackers to
    	inject arbitrary web script or HTML via crafted HTML entities.
    
    CVE-2010-2228
    	A Cross-site scripting (XSS) vulnerability in the MNET
    	access-control interface allows remote attackers to inject
    	arbitrary web script or HTML via vectors involving extended
    	characters in a username.
    
    CVE-2010-2229
    	Multiple cross-site scripting (XSS) vulnerabilities in
    	blog/index.php allow remote attackers to inject arbitrary web
    	script or HTML via unspecified parameters.
    
    CVE-2010-2230
    	The KSES text cleaning filter in lib/weblib.php does
    	not properly handle vbscript URIs, which allows remote
    	authenticated users to conduct cross-site scripting (XSS)
    	attacks via HTML input.
    
    CVE-2010-2231
    	A Cross-site request forgery (CSRF) vulnerability in
    	report/overview/report.php in the quiz module allows remote
    	attackers to hijack the authentication of arbitrary users for
    	requests that delete quiz attempts via the attemptid
    	parameter.
    
    This security update switches to a new upstream version and requires
    database updates.  After installing the fixed package, you must visit
     and follow the update instructions.
    
    For the stable distribution (lenny), these problems have been fixed in
    version 1.8.13-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1.9.9.dfsg2-1.
    
    We recommend that you upgrade your moodle package.
