CRLF injection in httplib2
Impact
Attacker controlling unescaped part of uri for httplib2.Http.request() could change request headers and body, send additional hidden requests to same server.
Impacts software that uses httplib2 with uri constructed by string concatenation, as opposed to proper urllib building with escaping.
Patches
Problem has been fixed in 0.18.0 Space, CR, LF characters are now quoted before any use. This solution should not impact any valid usage of httplib2 library, that is uri constructed by urllib.
Workarounds
Create URI with urllib.parse family functions: urlencode, urlunsplit.

In httplib2 before version 0.18.0, an attacker controlling unescaped part of uri for `httplib2.Http.request()` could change request headers and body, send additional hidden requests to same server. This vulnerability impacts software that uses httplib2 with uri constructed by string concatenation, as opposed to proper urllib building with escaping. This has been fixed in 0.18.0.
