An update that fixes 8 vulnerabilities, contains two features is now available.

Description:

This update for python3 fixes the following issues:

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


Update to 3.6.12 (bsc#1179193)

  o Ensure python3.dll is loaded from correct locations when Python is embedded
  o 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).
  o Prevent http header injection by rejecting control characters in
    http.client.putrequest(...).
  o Unpickling invalid NEWOBJ_EX opcode with the C implementation raises now
    UnpicklingError instead of crashing.
  o Avoid infinite loop when reading specially crafted TAR files using the
    tarfile module


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


Update to 3.6.11:

  o Disallow CR or LF in email.headerregistry. Address arguments to guard
    against header injection attacks.
  o 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)
  o 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.
