Package updates are available for Alibaba Cloud Linux 2.1903 that fix the following vulnerabilities: CVE-2018-18074: The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network. CVE-2018-20060: urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext. CVE-2019-11236: In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter.
