Critical Unauthenticated RCE Flaws in CUPS Printing Systems

A criticalset of unauthenticated Remote Code Execution RCE vulnerabilities in CUPS, affecting all GNU/Linux systems and potentially others, was disclosed today. These vulnerabilities allow a remote attacker to execute arbitrary code on a target system without valid credentials or prior access...

CVE-2024-47176

CUPS is a standards-based, open-source printing system, and cups-browsed contains network printing functionality including, but not limited to, auto-discovering print services and shared printers. cups-browsed binds to INADDRANY:631, causing it to trust any packet from any source, and can cause t...

CVE-2024-47076

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.
