+== Changes since 1.13.2 ==
+
+David Remahl of Apple's Product Security team has identified a number of
+security issues in previous releases of MediaWiki. Subsequent analysis by the
+MediaWiki development team expanded the scope of these vulnerabilities. The
+issues with a significant impact are as follows:
+
+* An XSS vulnerability affecting all MediaWiki installations between 1.13.0 and
+ 1.13.2. [CVE-2008-5249]
+* A local script injection vulnerability affecting Internet Explorer clients for
+ all MediaWiki installations with uploads enabled. [CVE-2008-5250]
+* A local script injection vulnerability affecting clients with SVG scripting
+ capability (such as Firefox 1.5+), for all MediaWiki installations with SVG
+ uploads enabled. [CVE-2008-5250]
+* A CSRF vulnerability affecting the Special:Import feature, for all MediaWiki
+ installations since the feature was introduced in 1.3.0. [CVE-2008-5252]
+
+XSS (cross-site scripting) vulnerabilities allow an attacker to steal an
+authorised user's login session, and to act as that user on the wiki. The
+authorised user must visit a web page controlled by the attacker in order to
+activate the attack. Intranet wikis are vulnerable if the attacker can
+determine the intranet URL.
+
+Local script injection vulnerabilities are like XSS vulnerabilities, except
+that the attacker must have an account on the local wiki, and there is no
+external site involved. The attacker uploads a script to the wiki, which another
+user is tricked into executing, with the effect that the attacker is able to act
+as the privileged user.
+
+CSRF vulnerabilities allow an attacker to act as an authorised user on the wiki,
+but unlike an XSS vulnerability, the attacker can only act as the user in a
+specific and restricted way. The present CSRF vulnerability allows pages to be
+edited, with forged revision histories. Like an XSS vulnerability, the
+authorised user must visit the malicious web page to activate the attack.
+
+These four vulnerabilities are all fixed in this release.
+
+David Remahl also reminded us of some security-related configuration issues:
+
+* By default, MediaWiki stores a backup of deleted images in the images/deleted
+ directory. If you do not want these images to be publically accessible, make
+ sure this directory is not accessible from the web. MediaWiki takes some steps
+ to avoid leaking these images, but these measures are not perfect.
+* Set display_errors=off in your php.ini to avoid path disclosure via PHP fatal
+ errors. This is the default on most shared web hosts.
+* Enabling MediaWiki's debugging features, such as $wgShowExceptionDetails, may
+ lead to path disclosure.
+
+Other changes in this release:
+
+* Avoid fatal error in profileinfo.php when not configured.
+* Add a .htaccess to deleted images directory for additional protection against
+ exposure of deleted files with known SHA-1 hashes on default installations.
+* Avoid streaming uploaded files to the user via index.php. This allows
+ security-conscious users to serve uploaded files via a different domain, and
+ thus client-side scripts executed from that domain cannot access the login
+ cookies. Affects Special:Undelete, img_auth.php and thumb.php.
+* When streaming files via index.php, use the MIME type detected from the
+ file extension, not from the data. This reduces the XSS attack surface.
+* Blacklist redirects via Special:Filepath. Such redirects exacerbate any
+ XSS vulnerabilities involving uploads of files containing scripts.
+* Internationalisation updates.

-
- #!/usr/bin/env php
- <?php
- require 'Test.php';
-
- plan($num); # plan $num tests
- # or
- plan('no_plan'); # We don't know how many
- # or
- plan('skip_all'); # Skip all tests
- # or
- plan('skip_all', $reason); # Skip all tests with a reason
-
- diag('message in test output') # Trailing \n not required
-
- # $test_name is always optional and should be a short description of
- # the test, e.g. "some_function() returns an integer"
-
- # Various ways to say "ok"
- ok($got == $expected, $test_name);
-
- # Compare with == and !=
- is($got, $expected, $test_name);
- isnt($got, $expected, $test_name);
-
- # Run a preg regex match on some data
- like($got, $regex, $test_name);
- unlike($got, $regex, $test_name);
-
- # Compare something with a given comparison operator
- cmp_ok($got, '==', $expected, $test_name);
- # Compare something with a comparison function (should return bool)
- cmp_ok($got, $func, $expected, $test_name);
-
- # Recursively check datastructures for equalness
- is_deeply($got, $expected, $test_name);
-
- # Always pass or fail a test under an optional name
- pass($test_name);
- fail($test_name);
-
- # TODO tests, these are expected to fail but won't fail the test run,
- # unexpected success will be reported
- todo_start("integer arithmetic still working");
- ok(1 + 2 == 3);

-=head1 DESCRIPTION
-
-F<Test.php> is an implementation of Perl's L<Test::More> for PHP. Like
-Test::More it produces language agnostic TAP output (see L<TAP>) which
-can then be gathered, formatted and summarized by a program that
-understands TAP such as prove(1).
-
-=head1 HOWTO
-
-First place the F<Test.php> in the project root or somewhere else in
-the include path where C<require> and C<include> will find it.
-
-Then make a place to put your tests in, it's customary to place TAP
-tests in a directory named F<t> under the root but they can be
-anywhere you like. Make a test in this directory or one of its subdirs
-and try running it with php(1):
-
- $ php t/pass.t
- 1..1
- ok 1 This dummy test passed
-
-The TAP output consists of very simple output, of course reading
-larger output is going to be harder which is where prove(1) comes
-in. prove is a harness program that reads test output and produces
-reports based on it:
-
- $ prove t/pass.t
- t/pass....ok
- All tests successful.
- Files=1, Tests=1, 0 wallclock secs ( 0.03 cusr + 0.02 csys = 0.05 CPU)
-
-To run all the tests in the F<t> directory recursively use C<prove -r
-t>. This can be put in a F<Makefile> under a I<test> target, for
-example:
-
- test: Test.php
- prove -r t
-
-For reference the example test file above looks like this, the shebang
-on the first line is needed so that prove(1) and other test harness
-programs know they're dealing with a PHP file.
-
- #!/usr/bin/env php
- <?php
-
- require 'Test.php';
-
- plan(1);
- pass('This dummy test passed');
- ?>

-Documenting the MediaWiki User object.
-
-(DISCLAIMER: The documentation is not guaranteed to be in sync with
-the code at all times. If in doubt, check the table definitions
-and User.php.)
-
-Database fields:
-
- user_id
- Unique integer identifier; primary key. Sent to user in
- cookie "{$wgDBname}UserID".
-
- user_name
- Text of full user name; title of "user:" page. Displayed
- on change lists, etc. Sent to user as cookie "{$wgDBname}UserName".
- Note that user names can contain spaces, while these are
- converted to underscores in page titles.
-
- user_rights
- Comma-separated list of rights. Right now, only "sysop",
- "developer", "bureaucrat", and "bot" have meaning.
-
- user_password
- Salted md5 hash of md5-hashed user login password. If user option to
- remember password is set, an md5 password hash is stored in cookie
- "{$wgDBname}UserPassword". The original password and the hashed password
- can be compared to the salted-hashed-hashed password.
-
- user_newpassword
- Hash for randomly generated password sent on 'send me a new password'.
- If a match is made on login, the new password will replace the old one.
-
- user_email
- User's e-mail address. (Optional, used for user-to-user
- e-mail and password recovery.)
-
- user_options
- A urlencoded string of name=value pairs to set various
- user options.
-
- user_touched
- Timestamp updated when the user logs in, changes preferences, alters
- watchlist, or when someone edits their user talk page or they clear
- the new-talk field by viewing it. Used to invalidate old cached pages
- from the user's browser cache.
-
- user_real_name
- "Real name" optionally used in some metadata lists.
-
-The user object encapsulates all of the settings, and clients
-classes use the getXXX() functions to access them. These functions
-do all the work of determining whether the user is logged in,
-whether the requested option can be satisfied from cookies or
-whether a database query is needed. Most of the settings needed
-for rendering normal pages are set in the cookie to minimize use
-of the database.
-
-Options
- The user_options field is a list of name-value pairs. The
- following option names are used at various points in the system:
