    Several vulnerabilities have been discovered in mediawiki, a web-based wiki
    engine.  The following issues have been identified:
    
    Insufficient input sanitization in the CSS validation code allows editors
    to display external images in wiki pages.  This can be a privacy concern
    on public wikis as it allows attackers to gather IP addresses and other
    information by linking these images to a web server under their control.
    
    Insufficient permission checks have been found in thump.php which can lead
    to disclosure of image files that are restricted to certain users
    (e.g. with img_auth.php).
    
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1.12.0-2lenny4.
    
    For the testing distribution (squeeze), this problem has been fixed in
    version 1:1.15.2-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1:1.15.2-1.
