libreoffice - security update

It was discovered that missing input sanitising in Libreoffice’s filter
for HWP documents may result in the execution of arbitrary code if a
malformed document is opened.

For the oldstable distribution (wheezy), this problem has been fixed in
version 1:3.5.4+dfsg2-0+deb7u4.

For the stable distribution (jessie), this problem has been fixed in
version 1:4.3.3-2+deb8u1.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your libreoffice packages.
