This update for python36 fixes the following issues :
buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution (bsc#1181126, CVE-2021-3177).
Provide the newest setuptools wheel (bsc#1176262, CVE-2019-20916) in their correct form (bsc#1180686).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
