------------------------------------

[~jensg][~xiaoqin.fu] i think push a public CVE before talk about it in jira is 
not a good idea, it will be a little negative.

If you worry about it, i`m happy to work together with to solve this problem.

as my experiense, the bugs from taint paths always exist in special using 
method.

we need more information to repeat that situation.

>             Project: Thrift
>          Issue Type: Bug
>          Components: Java - Library
>    Affects Versions: 0.11.0, 0.12.0

>    Operations: During Apache Thrift integration testing, I developed a 
> calculator application with a client and a server. The client sent a 
> computational command and get the result from the server. After I applied 
> dynamic taint analyzer (distTaint), I found bugs from taint paths finally.

> I am going to submit a CVE, so please confirm this is not a true positive.
