Bug 499632 – <www-apps/mediawiki-{1.19.11,1.21.5,1.22.2}: remote code execution if file upload support for DjVu or PDF files is enabled (CVE-2014-1610)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Alex Xu (Hello71) 2014-01-28 21:46:11 UTC]

I am almost entirely sure that www-apps/mediawiki:1.20* is also affected, due to the wording of the announce mail and its non-existence on the official download list. https://www.mediawiki.org/wiki/Download

> I would like to announce the release of MediaWiki 1.22.2, 1.21.5 and
> 1.19.11.
> 
> Your MediaWiki installation is affected by a remote code execution
> vulnerability if you have enabled file upload support for DjVu (natively
> supported by MediaWiki) or PDF files (in combination with the PdfHandler
> extension). Neither file type is enabled by default in MediaWiki
> installations. If you are affected, we strongly urge you to update
> immediately.

> Affected supported versions: All

> * Netanel Rubin from Check Point discovered a remote code execution
> vulnerability in MediaWiki's thumbnail generation for DjVu files. Internal
> review also discovered similar logic in the PdfHandler extension, which
> could be exploited in a similar way. (CVE-2014-1610)

Bumped. 1.20.x was EOL'd, and was pruned from the tree due to a previous security issue.
