{"id":"USN-7912-2","summary":"cups vulnerability","details":"USN-7912-1 fixed vulnerabilities in CUPS. This update provides the\ncorresponding update for Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu\n20.04 LTS.\n\nOriginal advisory details:\n\n Johannes Meixner and Paul Zirnik discovered that CUPS incorrectly handled\n clients that send messages slowly. A remote attacker could possibly use\n this issue to cause CUPS to stop responding, resulting in a denial of\n service. (CVE-2025-58436)\n\n In addition, this update fixes a regression introduced in USN-7897-1 which\n resulted in certain invalid configuration file directives to cause the\n CUPS daemon to fail to start.\n","modified":"2026-04-22T11:46:18.031680Z","published":"2025-12-04T18:22:26Z","related":["UBUNTU-CVE-2025-58436"],"upstream":["CVE-2025-58436","UBUNTU-CVE-2025-58436"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7912-2"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-58436"},{"type":"REPORT","url":"https://launchpad.net/bugs/2133207"}],"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":{"binaries":[{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-bsd"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-client"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-common"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-core-drivers"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-daemon"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-ipp-utils"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-ppdc"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"cups-server-common"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"libcups2"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"libcupscgi1"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"libcupsimage2"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"libcupsmime1"},{"binary_version":"2.1.3-4ubuntu0.11+esm12","binary_name":"libcupsppdc1"}],"availability":"Available
