Fedora 17 : mediawiki-1.19.5-1.fc17 (2013-6170)

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.
https://bugzilla.wikimedia.org/show_bug.cgi?id=46859

*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.
