Summary
Red Hat Security Advisory: python-jinja2 security update

Notes

Topic
An update for python-jinja2 is now available for Red Hat Enterprise Linux 9.2 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * jinja2: Jinja has a sandbox breakout through indirect reference to format method (CVE-2024-56326) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

          "text": "A flaw was found in the Jinja package. In affected versions of Jinja, 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 that execute untrusted templates. Jinja\u0027s sandbox does catch calls to str.format and ensures they don\u0027t escape the sandbox. However, storing a reference to a malicious string\u0027s format method is possible, then passing that to a filter that calls it. No such filters are built into Jinja but could be present through custom filters in an application. After the fix, such indirect calls are also handled by the sandbox.",
