An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib
in Python 3.x through 3.7.3. CRLF injection is possible if the attacker
controls a url parameter, as demonstrated by the first argument to
urllib.request.urlopen with \r\n (specifically in the path component of a
URL that lacks a ? character) followed by an HTTP header or a Redis
command. This is similar to the CVE-2019-9740 query string issue. This is
fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1,
v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11,
v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.4, v3.7.4rc1, v3.7.4rc2,
v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1,
v3.7.9.
