CVE-2012-4449 — Vulnerability in org.apache.hadoop:hadoop-client —...

CRITICAL

Use of a Broken or Risky Cryptographic Algorithm in Apache Hadoop

Published May 17, 2022Updated November 8, 2023Source: osv

Summary

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.
