Bump bleach from 2.1.4 to 3.1.4

Zilio, Nicola requested to merge dependabot/pip/bleach-3.1.4 into master

Created by: dependabot[bot]

Bumps bleach from 2.1.4 to 3.1.4.

Changelog

Sourced from bleach's changelog.

Version 3.1.4 (March 24th, 2020)

Security fixes

  • bleach.clean behavior parsing style attributes could result in a regular expression denial of service (ReDoS).

    Calls to bleach.clean with an allowed tag with an allowed style attribute were vulnerable to ReDoS. For example, bleach.clean(..., attributes={'a': ['style']}).

    This issue was confirmed in Bleach versions v3.1.3, v3.1.2, v3.1.1, v3.1.0, v3.0.0, v2.1.4, and v2.1.3. Earlier versions used a similar regular expression and should be considered vulnerable too.

    Anyone using Bleach <=v3.1.3 is encouraged to upgrade.
