CVE-2017-3166
HighSummary
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.
Risk Assessment
Organizations may be exposed to unauthorized access to sensitive data, potentially leading to information leaks and privacy violations.
Recommendation
It is recommended to restrict read permissions for files in encryption zones and to upgrade to the latest version of Apache Hadoop 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-2017-7669High
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.
- 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.
Original NVD description (English source)
In Apache Hadoop versions 2.6.1 to 2.6.5, 2.7.0 to 2.7.3, and 3.0.0-alpha1, if a file in an encryption zone with access permissions that make it world readable is localized via YARN's localization mechanism, that file will be stored in a world-readable location and can be shared freely with any application that requests to localize that file.
