[Pkg-mediawiki-devel] Bug#773654: mediawiki: Security issue: thumb.php outputs wikitext message as raw HTML

[Sebastien Delafond]

Package: mediawiki
Version: 1:1.19.20+dfsg-2.1
Severity: important
Tags: upstream patch

>From upstream bug T76686 (still not public): thumb.php outputs
wikitext message as raw HTML, which could lead to xss. Permission to
edit MediaWiki namespace is required to exploit this.

The upstream patch fixing this is at
https://github.com/wikimedia/mediawiki/commit/fdd3f464ef9aa7f3276a2a8dddc85e3769cfda83,
and I have uploaded 1:1.19.20+dfsg-2.2 to DELAYED/2, that includes
it. The corresponding debdiff is included at the end of this email.

Cheers,
