How to fix?

Upgrade RHEL:8 python3-libs to version 0:3.6.8-47.el8_6 or higher.
This issue was patched in RHSA-2022:6457.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-libs package and not the python3-libs package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9
