Alpine: multiple py3-jinja2 packages: security update to 1.11.3-r0

medium Tenable Self-Hosted Container Security Plugin ID 424392

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the
 `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most
 exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format
 user content instead of the urlize filter, or by implementing request timeouts and limiting process
 memory. (CVE-2020-28493)
