Catch urllib3.exceptions.SSLError in Response.iter_content

[anadius]

I believe requests should catch that and raise requests.exceptions.SSLError:

Traceback (most recent call last):
  File "urllib3\response.py", line 438, in _error_catcher
  File "urllib3\response.py", line 519, in read
  File "http\client.py", line 465, in read
  File "socket.py", line 705, in readinto
  File "ssl.py", line 1273, in recv_into
  File "ssl.py", line 1129, in read
ssl.SSLError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:2536)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "tkinter\__init__.py", line 1921, in __call__
  File "tkinter\__init__.py", line 839, in callit

This is requests 2.26.0.

That's some edge case and I've seen that happen only once (this is automatic error report from my program so I don't know any details, it's anonymous). I'm not trying to solve the problem, I just want to be able to catch requests.exceptions.SSLError instead of urllib3.exceptions.SSLError.

Thanks for reporting the issue @anadius. We've definitely had a few cases where either new or rarely raised exceptions from urllib3 leak through. I've added #6057 as a proposal to handle this.

We've merged #6057, so I'd expect this change to be available in the next release.
