Alpine: multiple py3-jinja2 packages: security update to 3.1.6-r0

medium Tenable Cloud Security Plugin ID 421121

Description

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

 - Jinja is an extensible templating engine. Prior to 3.1.6, an oversight in how the Jinja sandboxed
 environment interacts with the |attr filter allows an attacker that controls the content of a template to
 execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a
 template. Whether that is the case depends on the type of application using Jinja. This vulnerability
 impacts users of applications which execute untrusted templates. Jinja's sandbox does catch calls to
 str.format and ensures they don't escape the sandbox. However, it's possible to use the |attr filter to
 get a reference to a string's plain format method, bypassing the sandbox. After the fix, the |attr filter
 no longer bypasses the environment's attribute lookup. This vulnerability is fixed in 3.1.6.
