CVE-2024-47076 (GCVE-0-2024-47076)

Vulnerability from cvelistv5

Published

2024-09-26 21:18

Modified

2024-09-28 03:55

Severity ?

8.6 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N

CWE

CWE-20 - Improper Input Validation

Summary

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.
