Description Agostino Sarubbo gentoo-dev 2013-05-01 10:12:38 UTC
From ${URL} :

Two flaws were corrected in the recently-released MediaWiki 1.20.5 and 1.19.6 releases:

* Jan Schejbal / reported that SVG script filtering could be bypassed for Chrome and 
Firefox clients by using an encoding that MediaWiki understood, but these browsers interpreted as 
UTF-8. [1]

* Internal review discovered that extensions were not given the opportunity to disable a password 
reset, which could lead to circumvention of two-factor authentication. [2]


@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not

CVE-2013-2032 (
  MediaWiki before 1.19.6 and 1.20.x before 1.20.5 does not allow extensions
  to prevent password changes without using both Special:PasswordReset and
  Special:ChangePassword, which allows remote attackers to bypass the intended
  restrictions of an extension that only implements one of these blocks.

CVE-2013-2031 (
  MediaWiki before 1.19.6 and 1.20.x before 1.20.5 allows remote attackers to
  conduct cross-site scripting (XSS) attacks, as demonstrated by a CDATA
  section containing valid UTF-7 encoded sequences in a SVG file, which is
  then incorrectly interpreted as UTF-8 by Chrome and Firefox.
