REDHAT-BUG-571926: Medium severity Wikimedia MediaWiki vulnerability

MediaWiki upstream has released new v1.15.2 version: http://lists.wikimedia.org/pipermail/mediawiki-announce/2010-March/000088.html

of MediaWiki fixing two security issues (from upstream announcement):

a, "A CSS validation issue was discovered which allows editors to display external images in wiki pages. This is a privacy concern on public wikis, since a malicious user may link to an image on a server they control, which would allow that attacker to gather IP addresses and other information from users of the public wiki. All sites running publicly-editable MediaWiki installations are advised to upgrade. All versions of MediaWiki (prior to this one) are affected."

CVE identifier of CVE-2010-1189 has been assigned to this.

--

b, "A data leakage vulnerability was discovered in thumb.php which affects wikis which restrict access to private files using imgauth.php, or some similar scheme. All versions of MediaWiki since 1.5 are affected.

Deleting thumb.php is a suitable workaround for private wikis which do not use $wgThumbnailScriptPath or $wgLocalRepo['thumbScriptUrl']."

CVE identifier of CVE-2010-1190 has been assigned to this.
