Overview

Affected versions of this package are vulnerable to Improper Input Validation via the cfGetPrinterAttributes5 function due to improper sanitization of IPP attributes returned from an IPP server. An attacker can manipulate the data processed by this function by injecting malicious IPP attributes, which are not properly sanitized before use. This can lead to the generation of incorrect or harmful outputs within the CUPS system.

Note: This vulnerability is being investigated and the advisory is being updated as new information is discovered.
