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.
