Debian Lenny: DSA-2041-1 Critical: MediaWiki CSRF Risk Resolved

It was discovered that mediawiki, a website engine for collaborative
work, is vulnerable to a Cross-Site Request Forgery login attack, which
could be used to conduct phishing or similar attacks to users via
affected mediawiki installations.

Note that the fix used breaks the login API and may require clients using it to
be updated.

For the stable distribution (lenny), this problem has been fixed in
version 1:1.12.0-2lenny5.

For the testing distribution (squeeze) and the unstable distribution (sid),
this problem has been fixed in version 1:1.15.3-1.


We recommend that you upgrade your mediawiki packages.
