Description

AI Translation Available

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.
