{"id":"USN-7912-1","summary":"cups vulnerability","details":"Johannes Meixner and Paul Zirnik discovered that CUPS incorrectly handled\nclients that send messages slowly. A remote attacker could possibly use\nthis issue to cause CUPS to stop responding, resulting in a denial of\nservice. (CVE-2025-58436)\n\nIn addition, this update fixes a regression introduced in USN-7897-1 which\nresulted in certain invalid configuration file directives to cause the CUPS\ndaemon to fail to start.","modified":"2026-04-22T11:04:19.756850Z","published":"2025-12-04T16:07:04Z","related":["UBUNTU-CVE-2025-58436"],"upstream":["CVE-2025-58436","UBUNTU-CVE-2025-58436"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7912-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-58436"},{"type":"REPORT","url":"https://launchpad.net/bugs/2133207"}],"affected":[{"package":{"name":"cups","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/cups@2.4.1op1-1ubuntu4.16?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.1op1-1ubuntu4.16"}]}],"versions":["2.3.3op2-7ubuntu2","2.4.1op1-1ubuntu1","2.4.1op1-1ubuntu2","2.4.1op1-1ubuntu3","2.4.1op1-1ubuntu4","2.4.1op1-1ubuntu4.1","2.4.1op1-1ubuntu4.2","2.4.1op1-1ubuntu4.4","2.4.1op1-1ubuntu4.6","2.4.1op1-1ubuntu4.7","2.4.1op1-1ubuntu4.8","2.4.1op1-1ubuntu4.9","2.4.1op1-1ubuntu4.10","2.4.1op1-1ubuntu4.11","2.4.1op1-1ubuntu4.12","2.4.1op1-1ubuntu4.15"],"ecosystem_specific":{"availability":"No
