{"id":"UBUNTU-CVE-2025-58436","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.","modified":"2026-04-22T19:57:20.240710Z","published":"2025-11-27T15:00:00Z","related":["USN-7912-1","USN-7912-2"],"upstream":["CVE-2025-58436"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-58436"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-58436"},{"type":"REPORT","url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-8wpw-vfgm-qrrr"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7912-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7912-2"}],"affected":[{"package":{"name":"cups","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/cups@2.1.3-4ubuntu0.11+esm12?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.3-4ubuntu0.11+esm12"}]}],"versions":["2.1.0-4ubuntu3","2.1.0-5","2.1.0-6","2.1.0-6ubuntu1","2.1.0-7","2.1.2-1","2.1.2-2","2.1.3-1","2.1.3-1build1","2.1.3-3","2.1.3-4","2.1.3-4ubuntu0.2","2.1.3-4ubuntu0.3","2.1.3-4ubuntu0.4","2.1.3-4ubuntu0.5","2.1.3-4ubuntu0.6","2.1.3-4ubuntu0.7","2.1.3-4ubuntu0.8","2.1.3-4ubuntu0.9","2.1.3-4ubuntu0.10","2.1.3-4ubuntu0.11","2.1.3-4ubuntu0.11+esm1","2.1.3-4ubuntu0.11+esm2","2.1.3-4ubuntu0.11+esm3","2.1.3-4ubuntu0.11+esm4","2.1.3-4ubuntu0.11+esm5","2.1.3-4ubuntu0.11+esm6","2.1.3-4ubuntu0.11+esm7","2.1.3-4ubuntu0.11+esm8","2.1.3-4ubuntu0.11+esm9","2.1.3-4ubuntu0.11+esm11"],"ecosystem_specific":{"availability":"Available
