This update disables those two commands by default. The new configuration option 4lw.commands.whitelist can be used to whitelist commands selectively (and the full set of commands can be restored with '*')

For the stable distribution (jessie), this problem has been fixed in version 3.4.5+dfsg-2+deb8u2.

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

We recommend that you upgrade your zookeeper packages.");
