Detail
| It was discovered that Zookeeper, a service for maintaining configuration information, didn't restrict access to the computationally expensive wchp/wchc commands which could result in denial of service by elevated CPU consumption. 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. |
