mediawiki: multiple vulnerabilities

Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.2 allows remote attackers to inject arbitrary web script or HTML via crafted Cascading Style Sheets (CSS) comments, aka "CSS injection vulnerability." (CVE-2011-0047)

MediaWiki before 1.16.1, when user or site JavaScript or CSS is enabled, allows remote attackers to conduct clickjacking attacks via unspecified vectors. (CVE-2011-0003)

api.php in MediaWiki before 1.15.5 does not prevent use of public caching headers for private data, which allows remote attackers to bypass intended access restrictions and obtain sensitive information by retrieving documents from an HTTP proxy cache that has been used by a victim. (CVE-2010-2787)

Cross-site scripting (XSS) vulnerability in profileinfo.php in MediaWiki before 1.15.5, when wgEnableProfileInfo is enabled, allows remote attackers to inject arbitrary web script or HTML via the filter parameter. (CVE-2010-2788)

Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.3, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .html at the end of the query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character. (CVE-2011-1578)

The checkCss function in includes/Sanitizer.php in the wikitext parser in MediaWiki before 1.16.3 does not properly validate Cascading Style Sheets (CSS) token sequences, which allows remote attackers to conduct cross-site scripting (XSS) attacks or obtain sensitive information by using the \2f\2a and \2a\2f hex strings to surround CSS comments. (CVE-2011-1579)

The transwiki import functionality in MediaWiki before 1.16.3 does not properly check privileges, which allows remote authenticated users to perform imports from any wgImportSources wiki via a crafted POST request. (CVE-2011-1580)
