Debian: DSA-4461-1 Moderate: Zookeeper Information Disclosure

Harrison Neil discovered that the getACL() command in Zookeeper, a
service for maintaining configuration information, did not validate
permissions, which could result in information disclosure.

For the stable distribution (stretch), this problem has been fixed in
version 3.4.9-3+deb9u2.

We recommend that you upgrade your zookeeper packages.

For the detailed security status of zookeeper please refer to
its security tracker page at:
