Package        : mediawiki
Vulnerability  : several
Problem type   : remote
Debian-specific: no
Debian bug     : none
CVE ID         : none assigned yet

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.
