Ubuntu Security Notice 7043-4 - USN-7043-1 fixed vulnerabilities in cups-filters. This update improves the fix for CVE-2024-47176 by removing support for the legacy CUPS printer discovery protocol entirely. Simone Margaritelli discovered that the cups-filters cups-browsed component could be used to create arbitrary printers from outside the local network. In combination with issues in other printing components, a remote attacker could possibly use this issue to connect to a system, created manipulated PPD files, and execute arbitrary code when a printer is used. This update disables support for the legacy CUPS printer discovery protocol. Simone Margaritelli discovered that cups-filters incorrectly sanitized IPP data when creating PPD files. A remote attacker could possibly use this issue to manipulate PPD files and execute arbitrary code when a printer is used.
All an attacker needs to exploit flaws in the Common Unix Printing System is a few seconds and less than 1 cent in computing costs.
This article explores the Linux vulnerability discovered by Simone Margaritelli, which, according to cybersecurity companies Uptycs and Akamai,…
Debian Linux Security Advisory 5778-1 - Simone Margaritelli reported several vulnerabilities in cups-filters. Missing validation of IPP attributes returned from an IPP server and multiple bugs in the cups-browsed component can result in the execution of arbitrary commands without authentication when a print job is started.
Red Hat Security Advisory 2024-7346-03 - An update for cups-filters is now available for Red Hat Enterprise Linux 9. Issues addressed include a code execution vulnerability.

A new set of security vulnerabilities has been disclosed in the OpenPrinting Common Unix Printing System (CUPS) on Linux systems that could permit remote command execution under certain conditions. "A remote unauthenticated attacker can silently replace existing printers' (or install new ones) IPP urls with a malicious one, resulting in arbitrary command execution (on the computer) when a print
TL;DR: All versions of Red Hat Enterprise Linux (RHEL) are affected by CVE-2024-47076, CVE-2024-47175, CVE-2024-47176 and CVE-2024-47177, but are not vulnerable in their default configurations.Red Hat has been made aware of a group of vulnerabilities (CVE-2024-47076, CVE-2024-47175, CVE-2024-47176 and CVE-2024-47177) within OpenPrinting CUPS, an open source printing system that is prevalent in most modern Linux distributions, including RHEL. Specifically, CUPS provides tools to manage, discover and share printers for Linux distributions. By chaining this group of vulnerabilities together, an a
