Debian Security Advisory DSA-3100-1                   security@debian.org

Package        : mediawiki
CVE ID         : CVE-2014-9277
Debian Bug     : 772764

A flaw was discovered in mediawiki, a wiki engine: cross-domain-policy
mangling allows an article editor to inject code into API consumers
that deserialize PHP representations of the page from the API.

For the stable distribution (wheezy), this problem has been fixed in
version 1.19.20+dfsg-0+deb7u2.

We recommend that you upgrade your mediawiki packages.
