Debian Bug :=20
Multiple security issues were discovered in Python.
CVE-2019-20907
In Lib/tarfile.py, an attacker is able to craft a TAR
archive leading to an infinite loop when opened by tarfile.open,
because _proc_pax lacks header validation
CVE-2020-26116
http.client allows CRLF injection if the attacker controls
the HTTP request method
For Debian 9 stretch, these problems have been fixed in version
3.5.3-1+deb9u3.
We recommend that you upgrade your python3.5 packages.
