Description Jan Lieskovsky 2012-03-23 14:53:28 UTC

A weakness was found in the way MediaWiki, a wiki engine, performed generation of password reset tokens. A remote attacker could use various techniques to recover original PRNG information, that has been used for seeding / generation of a password reset token, possibly leading to ability to compromise the user account in question.

Comment 5 Vincent Danen 2013-05-08 20:38:57 UTC

The current version of mediawiki in Fedora is not vulnerable to this issue (1.19.4), however EPEL5 still provides mediawiki 1.14 as well as 1.16; EPEL6 and Fedora also provide 1.16.  It is unknown whether or not those versions are affected by this issue as they are no longer supported by upstream.
