551500 - Upgrade all MediaWiki 1.15.x instances to 1.15.2

Status: RESOLVED FIXED

Description

From MediaWiki security announcement released a few days ago:

Two security issues were discovered:

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.

A data leakage vulnerability was discovered in thumb.php which affects
wikis which restrict access to private files using img_auth.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'].
Alternatively, you can upgrade to MediaWiki 1.15.2 or backport the
patch below to whatever version of MediaWiki you are using.
