       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.
