[jira] [Updated] (FLINK-20996) Using a cryptographically weak
Pseudo Random Number Generator (PRNG)
[ https://issues.apache.org/jira/browse/FLINK-20996?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ya Xiao updated FLINK-20996:
----------------------------
Description:
We are a security research team at Virginia Tech. We are doing an empirical study about the usefulness of the existing security vulnerability detection tools. The following is a reported vulnerability by certain tools. We'll so appreciate it if you can give any feedback on it.
*Vulnerability Description:*
{color:#172b4d}In file {color}[flink/flink-end-to-end-tests/flink-stream-state-ttl-test/src/main/java/org/apache/flink/streaming/tests/verify/AbstractTtlStateVerifier.java,|https://github.com/apache/flink/blob/97bfd049951f8d52a2e0aed14265074c4255ead0/flink-end-to-end-tests/flink-stream-state-ttl-test/src/main/java/org/apache/flink/streaming/tests/verify/AbstractTtlStateVerifier.java] use java.util.Random instead of java.security.SecureRandom at Line 39.
*Security Impact:*
Java.util.Random is not cryptographically strong and may expose sensitive information to certain types of attacks when used in a security context.
*Useful Resources*:

*Solution we suggest:*
Replace it with SecureRandom
*Please share with us your opinions/comments if there is any:*
Is the bug report helpful?
