Fedora 19 : mediawiki-1.20.4-1.fc19 (2013-5874)

high Nessus Plugin ID 66219

Synopsis

The remote Fedora host is missing a security update.

Description

- An internal review discovered that specially crafted Lua function names could lead to XSS.
https://bugzilla.wikimedia.org/show_bug.cgi?id=46084

- Daniel Franke reported that during SVG parsing, MediaWiki failed to prevent XML external entity (XXE) processing. This could lead to local file disclosure, or potentially remote command execution in environments that have enabled expect:// handling.

- Internal review also discovered that Special:Import, and Extension:RSS failed to prevent XML external entity (XXE) processing.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected mediawiki package.
