* [3.7] bpo-43285 Make ftplib not trust the PASV response. (GH-24838) ↵Miss Islington (bot)2021-03-162-2/+34
| | | | | | | | | | | | | | | | | | | | (GH-24881) (GH-24883) The IPv4 address value returned from the server in response to the PASV command should not be trusted. This prevents a malicious FTP server from using the response to probe IPv4 address and port combinations on the client network. Instead of using the returned address, we use the IP address we're already connected to. This is the strategy other ftp clients adopted, and matches the only strategy available for the modern IPv6 EPSV command where the server response must return a port number and nothing else. For the rare user who _wants_ this ugly behavior, set a `trust_server_pasv_ipv4_address` attribute on your `ftplib.FTP` instance to True..

| | | | | | | | | | | | | | | | | ensurepip optionally installs or upgrades 'pip' and 'setuptools' using the version of those modules bundled with Python. The internal PIP installation routine by default temporarily uses its cache, if it exists. This is undesirable as Python builds and installations may be independent of the user running the build, whilst PIP cache location is dependent on the user's environment and outside of the build environment. At the same time, there's no value in using the cache while installing bundled modules. This change disables PIP caching when used in ensurepip.

It is fairly common to find malformed mime headers (especially content-disposition headers) where the parameter values, instead of being encoded to RFC standards, are "encoded" by doing RFC 2047 "encoded word" encoding, and then enclosing the whole thing in quotes. The processing of these malformed headers was incorrectly leaving the spaces between encoded words in the decoded text (whitespace between adjacent encoded words is supposed to be stripped on decoding). This changeset fixes the encoded word processing inside quoted strings (bare-quoted-string) to do correct RFC 2047 decoding by stripping that whitespace.
