Troubleshooting
Problem
The Python Analytic Executables allow you to use SSL interfaces within Python. See the following website of OpenSSL for a list of vulnerabilities that might affect the Python version that is installed with IBM® Netezza® Analytics. https://www.openssl.org/news/vulnerabilities.html To completely avoid vulnerability, you can block this feature when you use Python within IBM Netezza Analytics.
Diagnosing The Problem
Do the following steps:
- Check whether Python and SSL are working together by using the following call:
/nz/export/ae/languages/python/2.6/host/bin/python -c "import ssl; print ssl.cert_time_to_seconds(\"May 9 00:00:00 2007 GMT\");"
- If the output is as follows, SSL is working but might have a vulnerability problem:
Output: 1178683200.0
Resolving The Problem
You must disable SSL for Python by renaming the python lib.
To rename the python lib, enter the following command:
cd /nz/export/ae/sysroot/host/lib/
mv libssl.so.0.9.8b libssl.so.0.9.8b.org
You will then get an error when you import SSL:
/nz/export/ae/languages/python/2.6/host/bin/python -c "import ssl; print ssl.cert_time_to_seconds(\"May 9 00:00:00 2007 GMT\");"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/nz/export/ae/languages/python/2.6/host/lib/python2.6/ssl.py", line 60, in <module>
import _ssl # if we can't import it, let the error propagate
ImportError: /lib/libssl.so.6: undefined symbol: EVP_CIPHER_CTX_block_size
