cve 2025 58436

The tag cve 2025 58436 covers the denial-of-service vulnerability CVE-2025-58436 in the Common UNIX Printing System (CUPS). A single slow client can stall the CUPS daemon (cupsd), making the entire print service unusable. The vulnerability was fixed in CUPS version 2.4.15 and affects upstream packages prior to that release. CUPS is the de facto printing subsystem on most Linux and Unix-like systems, handling IPP, spooling, filters, and network printing, and often sits between Linux print servers and Windows clients in mixed environments. Discussions include patch guidance and mitigation strategies for administrators managing CUPS in enterprise or mixed-OS networks.
