CVE-2017-7669
HighSummary
In Apache Hadoop versions 2.8.0, 3.0.0-alpha1, and 3.0.0-alpha2, the LinuxContainerExecutor runs docker commands as root with insufficient input validation. When the docker feature is enabled, authenticated users can run commands as root.
Risk Assessment
The organization may be exposed to unauthorized actions by users, potentially leading to serious security breaches.
Recommendation
It is recommended to disable the docker feature or implement appropriate user permission restrictions to minimize risk.

An out-of-bounds write vulnerability in Apache Hadoop HDFS native client. Affects Apache Hadoop from 3.2.0 before 3.4.2. Users are recommended to upgrade to version 3.4.2, which fixes the issue.
- CVE-2017-3166High
In Apache Hadoop versions 2.6.1 to 2.6.5, 2.7.0 to 2.7.3, and 3.0.0-alpha1, files in encryption zones with world-readable permissions can be localized via YARN's localization mechanism, leading to their storage in a world-readable location.
- CVE-2017-3162High
HDFS clients interact with a servlet on the DataNode to browse the HDFS namespace. The NameNode query parameter is not validated in Apache Hadoop before 2.7.0.
- CVE-2016-6811High
In Apache Hadoop 2.x before 2.7.4, a user who can escalate to yarn user can possibly run arbitrary commands as root user.
- CVE-2016-5393High
In Apache Hadoop versions 2.6.x before 2.6.5 and 2.7.x before 2.7.3, a remote user who can authenticate with the HDFS NameNode can possibly run arbitrary commands with the same privileges as the HDFS service.
- CVE-2012-4449Critical
Apache Hadoop versions before 0.23.4, 1.x before 1.0.4, and 2.x before 2.0.2 generate token passwords using a 20-bit secret when Kerberos security features are enabled. This makes it easier for attackers to crack secret keys via a brute-force attack.
