Insight

Insight

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.
