CVE-2012-4449
October 30, 2017
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 Packages
org.apache.hadoop:hadoop-client (JAVA):
Affected version(s) >=1.0.1 <1.0.4
Fix Suggestion:
Update to version 1.0.4
org.apache.hadoop:hadoop-client (JAVA):
Affected version(s) >=0.20.2-cdh3u4 <0.23.4
