Update Information:

This is a security and bugfix release of MediaWiki 1.15.3.    Three security
issues are fixed in this update:    A CSS validation issue was discovered which
allows editors to display external images in wiki pages.    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.    MediaWiki
was found to be vulnerable to login CSRF. The upstrea authors recommend that all
public wikis should be upgraded if possible. The fix includes a breaking change
to the API login action. Any clients using it will need to be updated.
