Advisory Release Date: 2021-06-16 20:37 Pacific
Advisory Updated Date: 2021-06-22 22:42 Pacific
A flaw was found in Python. The built-in modules httplib and http.client (included in Python 2 and Python 3, respectively) do not properly validate CRLF sequences in the HTTP request method, potentially allowing manipulation to the request by injecting additional HTTP headers. The highest threat from this vulnerability is to confidentiality and integrity. (CVE-2020-26116)
In Python3's Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP. (CVE-2020-27619)
