["Phil Steitz (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/MATH-1182?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Phil Steitz closed MATH-1182.
-----------------------------
    Resolution: Invalid

None of the methods referenced are intended for cryptographic / secure token generating use.  Other PRNGs are available in the library and in most cases, user-supplied PRNGs may also be used.

>             Project: Commons Math
>          Issue Type: Bug

> We are currently using Commons-math3-3.3 and in the analysis for veracode, found this bug in these class:
> 1. FastMath.java (Line 813)
> 2. SynchronizedRandomGenerator.java (Line 78 and Line 85)
> 3. UniformIntegerDistribution.java (Line 164 and Line 172)
> 4. RandomAdaptor.java (Line 143  and 159)
> Type : Insufficient Entropy
> Description:
> Standard random number generators do not provide a sufficient amount of entropy when used for security purposes.
> Attackers can brute force the output of pseudorandom number generators such as rand().
> Recommendations:
> If this random number is used where security is a concern, such as generating a session key or session identifier, use
> a trusted cryptographic random number generator instead. These can be found on the Windows platform in the
> CryptoAPI or in an open source library such as OpenSSL.
> Thanks.
