For Debian 7 'Wheezy', these problems have been fixed in version
3.4.5+dfsg-2+deb7u1.

We recommend that you upgrade your zookeeper packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
