Red Hat has classified this issue as Important severity rather than Critical.\nPrint servers configured with ```\"printing = cups\"``` or ```\"printing = iprint\"```, and print servers that do not have the ```\"%J\"``` substitution character in the \"print command\" setting are not affected.\nBy default, Red Hat Enterprise Linux ships with Samba configured to use CUPS-based printing ```printing = cups```. Hence, although the vulnerable code is present, it is not exploitable in default RHEL configurations. \nIn addition, typical RHEL Samba deployments require authenticated access to submit print jobs, therefore Privileges Required are assessed as Low (PR:L).\nBecause exploitation depends on non-default Samba printing configurations and requires use of the %J substitution parameter within print command, the attack complexity is considered High (AC:H), reducing the likelihood of exploitation in standard deployments.", "threat_severity": "Important"}
