Descriptions

CUPS cups-browsed before 2.5b1 will send an HTTP POST request to an arbitrary destination and port in response to a single IPP UDP packet requesting a printer to be added, a different vulnerability than CVE-2024-47176. (The request is meant to probe the new printer but can be used to create DDoS amplification attacks.)

A flaw was found in cups-browsed. This vulnerability allows an attacker to launch DDoS amplification attacks via an HTTP POST request to an arbitrary destination and port in response to a single IPP UDP packet requesting a printer to be added.

This update for cups-filters fixes the following issues. Cups-browsed can be abused to initiate remote DDoS against third-party targets. Fixed lack of input sanitization in cfGetPrinterAttributes5.
