Subject: CVE requests for MediaWiki 1.26.1, 1.25.4, 1.24.5 and 1.23.12

We recently released security fixes for MediaWiki. I believe the first five
issues should have CVE's assigned. The last issue (T109724) requires that
the organization running the wiki also releases detailed page view data
publicly, and probably not worth tracking with a CVE. However I'm happy for
mitre to assign one of they think this generally qualifies.

* (T117899) XSS from wikitext when $wgArticlePath='$1'. Internal review
discovered an XSS vector when MediaWiki is configured with a non-standard

* (T119309) User::matchEditToken should use constant-time string
comparison. Internal review discovered that tokens were being compared as
strings, which could allow a timing attack. This should possibly have 2
CVE's assigned, one for the original patch to use hash_equals in (released as
part of MediaWiki 1.25, and backported to 1.24 and 1.23 as part of this
patch) and one to fix T119309, related to the debugging statement.

* (T118032) Error thrown by VirtualRESTService when POST variable starts
with '@'. Internal review discovered that MediaWiki was not sanitizing
parameters passed to the curl library, which could cause curl to upload
files from the webserver to an attacker.

* (T115522) Passwords generated by User::randomPassword() may be shorter
than $wgMinimalPasswordLength. MediaWiki user Frank R. Farmer reported that
the password reset token could be shorter than the minimum required
password length.

* (T97897) Incorrect parsing of IPs for global block. Wikimedia steward
Vituzzu reported that blocking IP addresses with zero-padded octets
resulted in a failure to block the IP address.

* (T109724) A combination of Special:MyPage redirects and pagecounts allows
an external site to know the wikipedia login of an user. Wikimedia
user Xavier Combelle reported a way to identify user, when detailed page
view data is also released.
