CVE-2024-47175 is a high-severity flaw (CVSS 8.6) affecting libppd, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 co
