Описание
CUPS is a standards-based, open-source printing system, and libcupsfilters contains the code of the filters of the former cups-filters package as library functions to be used for the data format conversion tasks needed in Printer Applications. The cfGetPrinterAttributes5 function in libcupsfilters does not sanitize IPP attributes returned from an IPP server. When these IPP attributes are used, for instance, to generate a PPD file, this can lead to attacker controlled data to be provided to the rest of the CUPS system.
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.
