A flaw was found in OpenPrinting CUPS. In certain conditions, a remote attacker can add a malicious printer or directly hijack an existing printer by replacing the valid IPP URL with a malicious one. Also, it is possible that due to a lack of validation of IPP attributes returned by the server, this issue allows attacker-controlled data to be used on the rest of the CUPS system.
See the security bulletin for a detailed mitigation procedure.
