Ubuntu 16.04 ESM : Apache ZooKeeper vulnerabilities (USN-4789-1)

high Nessus Plugin ID 183528

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4789-1 advisory.

 - Buffer overflow in the C cli shell in Apache Zookeeper before 3.4.9 and 3.5.x before 3.5.3, when using the cmd: batch mode syntax, allows attackers to have unspecified impact via a long command string.
 (CVE-2016-5017)

 - Two four letter word commands wchp/wchc are CPU intensive and could cause spike of CPU utilization on Apache ZooKeeper server if abused, which leads to the server unable to serve legitimate client requests.
 Apache ZooKeeper thru version 3.4.9 and 3.5.2 suffer from this issue, fixed in 3.4.10, 3.5.3, and later.
 (CVE-2017-5637)

 - No authentication/authorization is enforced when a server attempts to join a quorum in Apache ZooKeeper before 3.4.10, and 3.5.0-alpha through 3.5.3-beta. As a result an arbitrary end point could join the cluster and begin propagating counterfeit changes to the leader. (CVE-2018-8012)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
