Description

This security bulletin contains information about 1 security vulnerability.


1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2012-4449)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.
