- Newline characters have been escaped when performing uu
encoding to prevent them from overflowing into to content
section of the encoded file. This prevents malicious or
accidental modification of data during the decoding process.
- Fixes a ReDoS vulnerability in :mod:`http.cookiejar`. Patch
by Ben Caller.
- Fixed line numbers and column offsets for AST nodes for calls
without arguments in decorators.
- Disallow control characters in hostnames in http.client,
addressing CVE-2019-18348. Such potentially malicious header
injection URLs now cause a InvalidURL to be raised.
- Fix urllib.urlretrieve failing on subsequent ftp transfers
from the same host.
- Fix problems identified by GCC's -Wstringop-truncation
warning.
- AddRefActCtx() was needlessly being checked for failure in
PC/dl_nt.c.
- Prevent failure of test_relative_path in test_py_compile on
macOS Catalina.
- Fixed possible leak in :c:func:`PyArg_Parse` and similar
functions for format units "es#" and "et#" when the macro
:c:macro:`PY_SSIZE_T_CLEAN` is not defined.
