Description

Apache Hadoop 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, which makes it easier for context-dependent attackers to crack secret keys via a brute-force attack.

Affected configurations

• apache hadoop (<= 0.23.3) • apache hadoop 1.0.0 • apache hadoop 1.0.1 • apache hadoop 1.0.2 • apache hadoop 1.0.3 • apache hadoop 2.0.0 • apache hadoop 2.0.1 • apache hadoop 2.0.2
