Vulnerability Information

Severity: High
Vulnerability Published: 2016-09-21
Patch Published: 2016-09-21
CVE [?]: CVE-2016-5017, CVE-2017-5637
CPE [?]: cpe:/a:apache:zookeeper

Synopsis

The remote Apache ZooKeeper server is affected by multiple vulnerabilities.

Description

The version of Apache ZooKeeper listening on the remote host is prior to 3.4.10 or 3.5.x prior to 3.5.3. It is, therefore, affected by multiple vulnerabilities:

- A buffer overflow vulnerability in the C cli shell. Using the 'cmd:' batch mode syntax allows attackers to have an unspecified impact via a long command string. (CVE-2016-5017)

- A denial of service (DoS) vulnerability exists in due to two four letter word commands which cause CPU spikes on ZooKeeper server. An unauthenticated, remote attacker can exploit this issue to cause the application to stop responding. (CVE-2017-5637)

Solution

Update to Apache ZooKeeper 3.4.10 or 3.5.3 or later.
