I think that the first email about this was received from Timothy D. Morgan on 1/15/16. You should be able to get confirmation of this from Christian Heimes. I think that was a dark year for the PSRT.

I don't have the archives of the PSRT mailing list and I'm not sure that I was subscribed when "the" email was sent. Does someone have the date of this email? It's to complete the new entry in my doc: http://python-security.readthedocs.io/vuln/urllib ftpprotocolstreaminjection.html#urllib-ftp-protocol-stream-injection I don't want to blame anyone, I just want to collect data to help us to enhance our process to handle security vulnerabilities. FYI I tried to take care of a few security vulnerabilities recently, and as expected, each issue is more tricky than expected :-) While fixing http://bugs.python.org/issue30500 I noticed that urllib accepts newline characters in URLs. I don't know if it's deliberate or not... So I created a new issue http://bugs.python.org/issue30713 I updated expat from 2.1.1 to 2.2.0, but now the compilation fails in 2.7 on Windows with Visual Studio 2008. And just when I was done, expat 2.2.1 was released. I have to do the same job again :-) Victor
