Echo: jinja2: security update to 3.1.2-1+deb12u2

medium Tenable Cloud Security Plugin ID 459483

Description

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

 - Jinja is an extensible templating engine. Prior to 3.1.5, An oversight in how the Jinja sandboxed
 environment detects calls to str.format 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 store a reference to a
 malicious string's format method, then pass that to a filter that calls it. No such filters are built-in
 to Jinja, but could be present through custom filters in an application. After the fix, such indirect
 calls are also handled by the sandbox. This vulnerability is fixed in 3.1.5. (CVE-2024-56326)

Solution

Update the jinja2 library and its related packages to version 3.1.2-1+deb12u2 or later.
