MediaWiki 1.4.x (Legacy Releases)

[edit]
MediaWiki Stable Releases 1.4.x

1.4.15

[edit]
Released on 2006-03-26.

MediaWiki 1.4.15 is a security maintenance release.

A bug in decoding of certain encoded links could allow injection of raw HTML into page output; this could potentially lead to XSS attacks. Additionally, this release may display more correctly in IE7 betas.

1.4.14

[edit]
Released on 2006-01-19.

MediaWiki 1.4.14 is a security and bugfix maintenance release.

A bug in edit comment formatting could send PHP into an infinite loop if certain malformed links were included. In most installations, this would cause the script to fail after PHP's 30-second failsafe timeout.

1.4.13

[edit]

Released on 2006-01-05.

MediaWiki 1.4.13 is a security and bugfix maintenance release.

1.4.12

[edit]

Released on 2005-11-02.

MediaWiki 1.4.12 is a bugfix and security maintenance release.

Additional Notes:

  • A change in PHP 4.4.1 broke handling of extension and <pre> sections, causing garbage data to be inserted in output and saved edits. This version works around the change.
  • This release includes further corrections to the inline CSS style sanitation which works around a JavaScript "feature" on Microsoft Internet Explorer. Users of Microsoft Internet Explorer for Windows may be vulnerable to XSS injections on prior 1.4 releases; users of standards-compliant browsers are not vulnerable.
  • All publicly accessible wikis are recommended to upgrade to reduce the risk to visitors using Microsoft web browsers.

1.4.11

[edit]
Released on 2005-10-05.

MediaWiki 1.4.11 is a security maintenance release.

Additional Notes:

  • Unsafe handling of CSS by Microsoft Internet Explorer could be exploited to produce cross-site scripting attacks by JavaScript injection to clients running that browser.
  • This release blacklists several additional variants from use in HTML inline style attributes.
  • All publicly accessible wikis are recommended to upgrade to reduce the risk to visitors using Microsoft web browsers.

1.4.10

[edit]

Released on 2005-09-21.

MediaWiki 1.4.10 is a security maintenance release. Additional Notes:

  • A bug in edit submission handling could cause corruption of the previous revision in the database if an abnormal URL was used, such as those used by some spambots.
  • Affected releases:
    -1.4.x <= 1.4.9; fixed in 1.4.10
    -1.3.x <= 1.3.15; fixed in 1.3.16
  • 1.5 release candidates are not affected by this problem.

All publicly editable wikis are strongly recommended to upgrade immediately.

1.4 releases can be manually patched by changing this bit in EditPage.php: 

function importFormData( &$request ) {
   if( $request->wasPosted() ) {

to 

function importFormData( &$request ) {
   if( $request->getVal( 'action' ) == 'submit' && $request->wasPosted() ) {

1.4.9

[edit]
Released on 2005-08-29.

MediaWiki 1.4.9 is a security maintenance release.

  • See the full release notes.
  • It corrects two cross-site scripting security bugs:
    • <math> tags were handled incorrectly when TeX rendering support is off, as in the default configuration.
    • Extension or <nowiki> sections in Wiki table syntax could bypass HTML style attribute restrictions for cross-site scripting attacks against Microsoft Internet Explorer

1.4.8

[edit]
Released on 2005-08-23.

MediaWiki 1.4.8 is a bug fix and security maintenance release.

  • A flaw in the interaction between extensions and HTML attribute sanitization was discovered which could allow unauthorized use of offsite resources in style sheets, and possible exploitation of a JavaScript injection feature on Microsoft Internet Explorer.
  • This version expands the returned text and properly checks it before output.
  • Additionally, an update to skins/MonoBook.php ensures that sites using the default MonoBook skin will display correctly in the Internet Explorer 7 beta. (1.3 and 1.5 are not affected by this bug.)

1.4.7

[edit]
Released on 2005-07-16.

MediaWiki 1.4.7 is a stable series bugfix release.

Additional Notes:

  • Those affected by the following problems in 1.4.6 should upgrade:
    • Watchlist breakage on MySQL 3.23.x and with table prefix enabled
    • Possible breakage in watchlist, some image resizing modes on PHP 4.1.2
  • 1.4.6 included a fix for a cross-site scripting vulnerability, so anyone running older 1.4 releases is very strongly encouraged to upgrade as well.

Note to upgraders: current versions of MediaWiki are known to produce a large number of notice-level warnings under the newly released PHP 4.4.0. These appear however to be harmless; if you encounter them add error_reporting( E_ALL & ~E_NOTICE ); to your LocalSettings.php to suppress the notices.

  • PHP 5.1.0 beta 3 is known to be incompatible at this time.
  • MySQL 3.23.x and table prefix compatibility fix: restore old watchlist code (MediaZilla:2747, MediaZilla:2755)
  • PHP 4.1.2 compatibility fix: define floatval() equivalent if missing

MediaWiki 1.4.13

[edit]

(released January 5, 2006) MediaWiki 1.4.13 is a security maintenance release.Detection for uploads of Windows Metafile (.wmf) images has been added to help protect against a client-side vulnerability in unpatched Microsoft Windows operating systems. Sites which have enabled uploads and added non-standard file types (such as .ogg, .doc, or .pdf) should upgrade to this release to ensure that malicious .wmf files can't be uploaded with a fake extension; such files could put visitors to the site at risk. For more details on this, see: http://en.wikipedia.org/wiki/Windows_Metafile_vulnerability

MediaWiki 1.4.12

[edit]

(released 2005-11-02) MediaWiki 1.4.12 is a bugfix and security maintenance release.

[edit]

(released 2005-10-05) MediaWiki 1.4.11 is a security maintenance release. Unsafe handling of CSS by Microsoft Internet Explorer could be exploited to produce cross-site scripting attacks by JavaScript injection to clients running that browser. This release blacklists several additional variants from use in HTML inline style attributes. All publicly accessible wikis are recommended to upgrade to reduce the risk to visitors using Microsoft web browsers. Note: the MediaWiki 1.4.x series is not compatible with PHP 5.0.5 or higher. Upgrade to the 1.5.0 release if you require this version of PHP 5.

MediaWiki 1.4.10

[edit]

(released 2005-09-21) MediaWiki 1.4.10 is a security maintenance release. A bug in edit submission handling could cause corruption of the previous revision in the database if an abnormal URL was used, such as those used by some spambots. Affected releases:

These appear however to be harmless; if you encounter them add this to your LocalSettings.php to suppress the notices: error_reporting( E_ALL & ~E_NOTICE ); PHP 5.1.0beta3 is known to be incompatible at this time.

MediaWiki 1.4.6

[edit]

(released 2005-07-07) MediaWiki 1.4.6 is a bug fix and security update release. Incorrect escaping of a parameter in the page move template could be used to inject JavaScript code by getting a victim to visit a maliciously constructed URL. Users of vulnerable releases are recommended to upgrade to this release. Vulnerable versions:

  • 1.5 preview series: n <= 1.5beta2 vulnerable, fixed in 1.5beta3
  • 1.4 stable series: 1.4beta6 <= n <= 1.4.5 vulnerable, fixed in 1.4.6
  • 1.3 legacy series: not vulnerable This release also includes fixes for some rare bug annoying HTTP errors, a PHP 4.1.2 breakage bug, and works around some template limitations introduced in 1.4.5. See the changelog at the end of this file for a detailed list of bugs fixed.

MediaWiki 1.4.5

[edit]

(released 2005-06-03) MediaWiki 1.4.5 is a security update and bugfix release. Incorrect handling of page template inclusions made it possible to inject JavaScript code into HTML attributes, which could lead to cross-site scripting attacks on a publicly editable wiki. Vulnerable releases and fix:

  • 1.5 prerelease: fixed in 1.5alpha2
  • 1.4 stable series: fixed in 1.4.5
  • 1.3 legacy series: fixed in 1.3.13
  • 1.2 series no longer supported; upgrade to 1.4.5 strongly recommended This release also includes a number of bug fixes (see changelog below) and merges some large-server load balancing patches from Wikipedia. An experimental rate limiter for page edits and moves can be enabled with global, per-IP, per-subnet, or per-user bases. See configuration options in includes/DefaultSettings.php

MediaWiki 1.4.4

[edit]

(released 2005-05-04) MediaWiki 1.4.4 is a bugfix release for the 1.4 stable release series. Some bugs in the installer/updater and refreshLinks maintenance script were introduced in the last release and have been corrected.

MediaWiki 1.4.3

[edit]

(released 2005-04-28) MediaWiki 1.4.3 is a bugfix release for the 1.4 stable release series. Chiefly, this fixes a compatibility problem with PHP 5 and a minor link table corruption bug on initial page save.

MediaWiki 1.4.2

[edit]

(released 2005-04-20) MediaWiki 1.4.2 is a security and bug fix release for the 1.4 stable release series. A cross-site scripting injection vulnerability was discovered, which affects only MSIE clients and is only open if MediaWiki has been manually configured to run output through HTML Tidy ($wgUseTidy ). Several other bugs are fixed in this release, see the changelog below. All new installations are highly recommended to use 1.4.2 instead of1.3.x; 1.3.x users should consider upgrading for bug fixes and new features. Ealier 1.4.x release and beta users should upgrade to this release for relevant bug fixes; see the changelog later in this file. If you have trouble, remember to read this whole file and the online FAQ page before asking for help: http://meta.wikimedia.org/wiki/MediaWiki_FAQ

READ THIS FIRST: Upgrading

[edit]

If upgrading from an older release, see the notes in the file UPGRADE. There are a couple of minor database changes from the beta releases, and somewhat larger changes from 1.3.x. Upgrading from a previous 1.4.x stable release installation should generally only require copying the new files over the old ones.

READ THIS FIRST, TOO: MySQL 4.1 AND 5.0

[edit]

MySQL 5.0 is a beta release, not yet ready for production use. If you are using it, the notes below about 4.1 apply to you too. If you have the choice of MySQL 4.0 or MySQL 4.1 and don't need 4.1 for some other application, you should consider sticking with 4.0 for the moment. 4.1 may require you to do extra fiddling to get things to work due to changes that aren't fully backwards-compatible. MySQL 4.1 has changed the authentication protocol in an incompatible way; many PHP installations still use the older client libraries and CANNOT CONNECT TO THE SERVER WITH A PASSWORD without some changes. See: http://dev.mysql.com/doc/mysql/en/Old_client.html If MySQL is set with utf-8 as the default character set, installation may fail with "key too long" errors. Set the default charset to 'latin1' for installation and it should work. The mysqldump backup generator now applies an automatic conversion to UTF-8, which may irretrivably corrupt your data. Pass the -charset option with the original default charset (eg 'latin1') to skip the conversion.

READ THIS FIRST IF RUNNING ON A WINDOWS SERVER

[edit]

MediaWiki is tested and deployed primarily under the Apache web server on Linux Unix systems. There are known to be problems running on Microsoft's IIS which are not fully resolved. If you have a choice, try running under Apache on Windows, or on a Unix/Linux box instead. If you're having trouble with blank pages on IIS and can't switch, try the workaround suggested in this bug report: http://bugzilla.wikimedia.org/show_bug.cgi?id=1763

New features

[edit]
  • 'Recentchanges Patrol' to mark new edits that haven't yet been viewed.
  • New, searchable deletion/upload/protection logs
  • Image gallery generation (Special:Newimages and <gallery> tag)
  • SVG rasterization support (requires external support tools)
  • Users can select from the available localizations to override the default user interface language.
  • Traditional/Simplified Chinese conversion support
  • rel="nofollow" support to combat linkspam The current implementation adds this attribute to _all_ external URL links in wiki text (but not internal wiki links or interwiki links). To disable the attribute for _all_ external links, add this line to yourLocalSettings.php: $wgNoFollowLinks = false For background information on nofollow see: http://www.google.com/googleblog/2005/01/preventing-comment-spam.html

Installation and compatibility

[edit]
  • The default MonoBook theme now works with PHP 5.0
  • Installation on systems with PHP's safe mode or other oddities should work more reliably, as MonoBook no longer needs to create a compiled template file for the wiki to run.
  • A table prefix may be specified, to avoid conflicts with other web applications forced to share a database.
  • More thorough UTF-8 input validation; fixes non-ASCII uploaded filenames from Safari.
  • Command-line database upgrade script.

Customizability

[edit]
  • Default user options can now be overridden in LocalSettings.
  • Skins system more modular: templates and CSS are now in /skins/ New skins can be dropped into this directory and used immediately.
  • More extension hooks have been added.
  • Authentication plugin hook.
  • More internal code documentation, generated with phpdoc: http://www.mediawiki.org/docs/html/

Optimization

[edit]
  • For many operations, MediaWiki 1.4 should run faster and use less memory than MediaWiki 1.3. Page rendering is up to twice as fast. (Use a PHP accelerator such as Turck MMCache for best results with any PHP application, though!)
  • The parser cache no longer requires memcached, and is enabled by default. This avoids a lot of re-rendering of pages that have been shown recently, greatly speeding longer page views.
  • Support for compiled PHP modules to speed up page diff and Unicode validation/normalization. (Requires ability to compile and load PHP extensions).

What isn't ready yet

[edit]
  • A new user/groups permissions scheme has been held back to 1.5.
  • An experimental SOAP interface will be made available as an extension
  • PostgreSQL support is largely working, minus search and the installer. You can perform a manual installation.
  • E-mail notification of watched page changes and verification of user-submitted e-mail addresses is not yet included.
  • Log pages are not automatically imported into the new log table at upgrade time. A script to import old text log entries is incomplete, but may be available in later point releases.
  • Some localizations are still incomplete.

Changelog

[edit]

Important security updates

[edit]

A security audit found and fixed a number of problems. Users of MediaWiki 1.3.10 and earlier should upgrade to 1.3.11; users of 1.4 beta releases prior to 1.4rc1 should upgrade immediately.

Cross-site scripting vulnerability

[edit]

XSS injection points can be used to hijack session and authentication cookies as well as more serious attacks.

  • Media: links output raw text into an attribute value, potentially abusable for JavaScript injection. This has been corrected.
  • Additional checks added to file upload to protect against MSIE and Safari MIME-type autodetection bugs. As of 1.3.10/1.4beta6, per-user customized CSS and JavaScript is disabled by default as a general precaution. Sites which want this ability may set $wgAllowUserCss and $wgAllowUserJs in LocalSettings.php.

Cross-site request forgery

[edit]

An attacker could use JavaScript-submitted forms to perform various restricted actions by tricking an authenticated user into visiting a malicious web page. A fix for page editing in 1.3.10/1.4beta6 has been expanded in this release to other forms and functions. Authors of bot tools may need to update their code to include the additional fields.

Directory traversal

[edit]

An unchecked parameter in image deletion could allow an authenticated administrator to delete arbitary files in directories writable by the web server, and confirm existence of files not deletable.

Older issues

[edit]

Note that 1.4 beta releases prior to beta 5 include an input validation error which could lead to execution of arbitrary PHP code on the server. Users of older betas should upgrade immediately to the current version. Beta 6 also introduces the use of rel="nofollow" attributes on external links in wiki pages to reduce the effectiveness of wiki spam. This will cause participating search engines to ignore external URL links from wiki pages for purposes of page relevancy ranking.

Caveats

[edit]

Some output, particularly involving user-supplied inline HTML, may not produce 100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType = "application/xhtml+xml"; to test for remaining problem cases, but this is not recommended on live sites. (This must be set for MathML to display properly in Mozilla.) For notes on 1.3.x and older releases, see HISTORY.
