[DLA 654-1] libxfixes security update

Package : libxfixes
Version : 1:5.0-4+deb7u2
CVE ID : CVE-2016-7944
Debian Bug : 840442

It was discovered that there was a integer overflow in libxfixes, a library
providing a client interface to the X11 'XFIXES' extension.

The 32 bit field "rep.length" was not checked for validity, which allowed an
integer overflow on 32 bit systems. A malicious server could send INT_MAX as
"length" which was then multiplied by the size of XRectangle. In this case the
client would not read the whole data from server, getting out of sync.

For Debian 7 "Wheezy", this issue has been fixed in libxfixes version
1:5.0-4+deb7u2.

We recommend that you upgrade your libxfixes packages.
