   An update that fixes 8 vulnerabilities is now available.

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(???).
   * 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.
