NVD Description

Note: Versions mentioned in the description apply only to the upstream cups-printerapp package and not the cups-printerapp package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

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.
