Jens Geyer commented on THRIFT-4928:
------------------------------------
1) Why do we need to start the process with an CVE?
2) What is the actual problem?
3) What is the proposed fix?
4) Why do we need 3 similar tickets?
5) Why do we have to confirm the claim you made?
> Sensitive information about expected and actual reading lengths (len, got) is
> leaked from TIOStreamTransport to TTransport through a TTransportException

> Key: THRIFT-4928
> URL: https://issues.apache.org/jira/browse/THRIFT-4928
> Project: Thrift
> Issue Type: Bug
> Components: Java - Library
> Affects Versions: 0.11.0, 0.12.0
> Environment: Ubuntu 16.04.3 LTS
> Open JDK version "1.8.0_191" build 25.191-b12
> Reporter: xiaoqin.fu
> Priority: Major
>
> 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.
> The source: org.apache.thrift.transport.TIOStreamTransport:
> public int read(byte[] buf, int off, int len) throws TTransportException {
> if (inputStream_ == null) {
> throw new TTransportException(TTransportException.NOT_OPEN, "Cannot
> read from null inputStream");
> }
> int bytesRead;
> ......
> bytesRead = inputStream_.read(buf, off, len);
> ......
> }
>
> The sink: org.apache.thrift.transport.TTransport,
> public int readAll(byte[] buf, int off, int len)
> throws TTransportException {
> ......
> if (ret <= 0) {
> throw new TTransportException(
> "Cannot read. Remote side has closed. Tried to read "
> + len
> + " bytes, but only got "
> + got
> + " bytes. (This is often indicative of an internal
> error on the server side. Please check your server logs.)");
> }
> ......
> }
> Sensitive information about expected and actual reading lengths (len, got)
> is leaked.
> The tainted path:
> org.apache.thrift.transport.TIOStreamTransport -->
> org.apache.thrift.transport.TTransport
>
> I am going to submit a CVE, so please confirm this is not a true positive.
