libxrender - security update

Tobias Stoeckmann from the OpenBSD project has discovered a number of
issues in the way various X client libraries handle the responses they
receive from servers. Insufficient validation of data from the X server
could cause out of boundary memory writes in the libXrender library
potentially allowing the user to escalate their privileges.

For Debian 7 Wheezy, these problems have been fixed in version
1:0.9.7-1+deb7u3.

We recommend that you upgrade your libxrender packages.
