NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-samba-test package and not the python3-samba-test package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the "print command" setting via the "%J" substitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system.
