CVE-2025-58436

MEDIUM5.1

OpenPrinting CUPS slow client can halt cupsd, leading to a possible DoS attack

Published Nov 29, 2025

Modified 1 months ago

No fix available

Details

OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to version 2.4.15, a client that connects to cupsd but sends slow messages, e.g. only one byte per second, delays cupsd as a whole, such that it becomes unusable by other clients. This issue has been patched in version 2.4.15.
