[Bug 1808476] Re: Please bump libssl1.1 dependency to at least >= 1.1.1, as headers leak constants

[Launchpad Bug Tracker]

This bug was fixed in the package python2.7 - 2.7.16-2

---------------
python2.7 (2.7.16-2) unstable; urgency=high

  [ Matthias Klose ]
  * CVE-2019-9636. Fix issue #36216: Add check for characters in netloc that
    normalize to separators. Closes: #924073.
  * CVE-2019-9948. Fix issue #35907: Stop urllib exposing the local_file schema
    (file://).

  [ Dimitri John Ledkov ]
  * Bump Build-Depedency and Dependency of libssl-dev and libss1.1 to
    1.1.1 or higher. As TLS1.3 constants leak into ssl module, thus one
    shouldn't mix and match python2.7 & libssl1.1. LP: #1808476

  Please bump libssl1.1 dependency to at least >= 1.1.1, as headers leak
  constants

Bug description:
  $ python -c 'import ssl; print(ssl.OP_NO_TLSv1_3)'

  Prints 0, for python2.7 built against 1.1.0 headers, yet prints
  536870912 when built against 1.1.1 irrespective of the runtime
  libssl1.1 library version.

  This may yield confusion, especially since ssl.OPENSSL_VERSION reports
  runtime libssl version, not the version of the libssl headers. Such
  that, e.g. it looks like ssl module is running against 1.1.1, has
  OP_NO_TLSv1_3 option, yet cannot actually use it to disable TLSv1.3.

  Also vice versa, python2.7 build against 1.1.1 can be installed with
  1.1.0 runtime library, and thus OP_NO_TLSv1_3 might be set, which is
  not understood by the runtime library.

  In libpython2.7-stdlib, please bump libssl1.1 version dep to
  "libssl1.1 (>= 1.1.1)" when building against libssl-dev >= 1.1.1.

  python3.x are not affected, as they started to exploit 1.1.1-only
  symbols/features, and thus already have an automatic dep on >= 1.1.1.
