[Python-modules-team] Bug#892252: src:python-bleach: URI values with character entities not properly sanitized

[Scott Kitterman]

Package: src:python-bleach
Version: 2.1.2-1
Severity: important
Tags: upstream, security


Version 2.1.3 (March 5th, 2018)
-------------------------------

**Security fixes**

* Attributes that have URI values weren't properly sanitized if the
  values contained character entities. Using character entities, it
  was possible to construct a URI value with a scheme that was not
  allowed that would slide through unsanitized.

  This security issue was introduced in Bleach 2.1. Anyone using
Bleach 2.1 is highly encouraged to upgrade.
