Description Hubert Kario 2015-09-29 07:32:35 EDT
Description of problem:
When a server receives a client initiated renegotiation and interleaved Application Data with Handshake messages in any of the subsequent handshakes, the connection is aborted with "unexpected record" error on the server side.

This causes applications like PostgreSQL JDBC driver to be incompatible with PostgreSQL.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. openssl req -x509 -newkey rsa -keyout localhost.key -out localhost.crt\
-nodes -batch
2. openssl s_server -key localhost.key -cert\

In another terminal:

3. pip install --pre tlslite-ng
4. git clone https://github.com/tomato42/tlsfuzzer.git

5. cd tlsfuzzer
6. PYTHONPATH=. python scripts/test-openssl-3712.py

Actual results:
140492755036064:error:140940F5:SSL routines:SSL3_READ_BYTES:unexpected record:s3_pkt.c:1421:

Expected results:
Test pass

Upstream is really reluctant to fix this behavior and I am not too confident of the change either.
