  <summary>Security update for python3</summary>
  <description>This update for python3 fixes the following issues:

- Fixed CVE-2020-27619 (bsc#1178009), where Lib/test/multibytecodec_support
  calls eval() on content retrieved via HTTP.
- Change setuptools and pip version numbers according to new wheels
- Handful of changes to make python36 compatible with SLE15 and SLE12
  (jsc#ECO-2799, jsc#SLE-13738)
- add triplets for mips-r6 and riscv
- RISC-V needs CTYPES_PASS_BY_REF_HACK

Update to 3.6.12 (bsc#1179193)

* Ensure python3.dll is loaded from correct locations when Python is embedded
* The __hash__() methods of ipaddress.IPv4Interface and ipaddress.IPv6Interface 
  incorrectly generated constant hash values of 32 and 128 respectively. This 
  resulted in always causing hash collisions. The fix uses hash() to generate 
  hash values for the tuple of (address, mask length, network address).
* Prevent http header injection by rejecting control characters in 
  http.client.putrequest(&#8230;).
* Unpickling invalid NEWOBJ_EX opcode with the C implementation raises now 
  UnpicklingError instead of crashing.
* Avoid infinite loop when reading specially crafted TAR files using the tarfile 
  module

- This release also fixes CVE-2020-26116 (bsc#1177211) and CVE-2019-20907 (bsc#1174091).

Update to 3.6.11:

- Disallow CR or LF in email.headerregistry. Address
  arguments to guard against header injection attacks.
- 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. (bsc#1155094)
- CVE-2020-8492: The AbstractBasicAuthHandler class
  of the urllib.request module uses an inefficient regular
  expression which can be exploited by an attacker to cause
  a denial of service. Fix the regex to prevent the
  catastrophic backtracking. Vulnerability reported by Ben
  Caller and Matt Schwager.
