Summary

The User::randomPassword function in MediaWiki before 1.23.12, 1.24.x before 1.24.5, 1.25.x before 1.25.4, and 1.26.x before 1.26.1 generates passwords smaller than $wgMinimalPasswordLength, which makes it easier for remote attackers to obtain access via a brute-force attack.

fine, as are '/wiki/$1'. A value such as '$1' or 'wiki/$1' is not and
will now throw an error.

(T119309) SECURITY: Use hash_compare() for edit token comparison.

(T118032) SECURITY: Don't allow cURL to interpret POST parameters
starting with '@' as file uploads.

(T115522) SECURITY: Passwords generated by User::randomPassword() can
no longer be shorter than $wgMinimalPasswordLength.

(T97897) SECURITY: Improve IP parsing and trimming. Previous behavior
could result in improper blocks being issued.

(T109724) SECURITY: Special:MyPage, Special:MyTalk,
Special:MyContributions and related pages no longer use HTTP redirects
and are now redirected by MediaWiki."
