GLSA-200502-33 : MediaWiki: Multiple vulnerabilities

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200502-33
(MediaWiki: Multiple vulnerabilities)

A security audit of the MediaWiki project discovered that
MediaWiki is vulnerable to several cross-site scripting and cross-site
request forgery attacks, and that the image deletion code does not
sufficiently sanitize input parameters.

Impact :

By tricking a user to load a carefully crafted URL, a remote
attacker could hijack sessions and authentication cookies to inject
malicious script code that will be executed in a user's browser session
in context of the vulnerable site, or use JavaScript submitted forms to
perform restricted actions. Using the image deletion flaw, it is also
possible for authenticated administrators to delete arbitrary files via
directory traversal.

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=www-apps/mediawiki-1.3.11'
