CVE-2024-47175Public exploitNetwork attack vector

Code execution via unsanitized IPP attributes

Published Sep 26, 2024 · Updated Nov 3, 2025

Improper input validation in OpenPrinting libppd 2.1b1 and earlier allows remote attackers to execute code via crafted IPP attributes. ppdCreatePPDFromIPP2 writes attacker-controlled IPP values into a generated PPD buffer without rejecting invalid response data. Exploitation requires a chain that obtains the attributes through a caller such as cfGetPrinterAttributes5 and processes the resulting directives with Foomatic.
