CVE-2018-20060 [CRITICAL] python-urllib3 vulnerabilities
python-urllib3 vulnerabilities
It was discovered that urllib3 incorrectly removed Authorization HTTP
headers when handled cross-origin redirects. This could result in
credentials being sent to unintended hosts. This issue only affected Ubuntu
16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2018-20060)
It was discovered that urllib3 incorrectly stripped certain characters from
requests. A remote attacker could use this issue to perform CRLF injection.
(CVE-2019-11236)
It was discovered that urllib3 incorrectly handled situations where a
desired set of CA certificates were specified. This could result in
certificates being accepted by the default CA certificates contrary to
expectations. This issue only affected Ubuntu 18.04 LTS, Ubuntu 18.10, and
Ubuntu 19.04. (CVE-2019-11324)
