DESCRIPTION:
Some vulnerabilities have been reported in MediaWiki, which can be
exploited by malicious users to delete arbitrary files, and by
malicious people to conduct cross-site scripting attacks and bypass
certain security restrictions.

1) Some unspecified input in the link formatting isn't properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of a vulnerable site.

2) Input passed to an unspecified parameter when deleting images
isn't properly sanitised. This can be exploited by authenticated
administrators to delete arbitrary files via directory traversal
attacks.

3) Various actions requiring authentication can be executed via an
off-site form. This can be exploited to execute various actions by
tricking an authenticated user into visiting a malicious website.

SOLUTION:
Update to version 1.3.11.
