Improper input validation in Openprinting Libppd
CVE-2024-47175
CUPS is a standards-based, open-source printing system, and `libppd` can be used for legacy PPD file support. The `libppd` function `ppdCreatePPDFromIPP2` does not sanitize IPP attributes when creating the PPD buffer. When used in combination with other functions such as `cfGetPrinterAttributes5`, can result in user controlled input and ultimately code execution via Foomatic. This vulnerability can be part of an exploit chain leading to remote code execution (RCE), as described in CVE-2024-47176.
