{"id":"UBUNTU-CVE-2026-64611","details":"A flaw was found in libcupsfilters. The cfIEEE1284NormalizeMakeModel() function enters an infinite loop when processing a printer-advertised IEEE-1284 device ID with an empty model field, causing sustained CPU consumption. A network-adjacent attacker could exploit this by broadcasting a specially crafted printer advertisement, leading to denial of service.","modified":"2026-07-29T10:18:03.390479814Z","published":"2026-07-23T11:16:00Z","upstream":["CVE-2026-64611"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-64611"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-64611"},{"type":"REPORT","url":"https://github.com/OpenPrinting/libcupsfilters/security/advisories/GHSA-rcq7-rv5g-j3r4"}],"affected":[{"package":{"name":"cups-filters","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/cups-filters?arch=source&distro=esm-infra%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.76-1","1.1.0-1","1.1.0-1build1","1.3.0-1","1.4.0-1","1.5.0-1","1.6.0-1","1.7.0-1","1.8.1-1","1.8.2-1","1.8.2-2","1.8.2-2ubuntu2","1.8.2-2ubuntu3","1.8.3-2ubuntu1","1.8.3-2ubuntu2","1.8.3-2ubuntu3","1.8.3-2ubuntu3.1","1.8.3-2ubuntu3.4","1.8.3-2ubuntu3.5","1.8.3-2ubuntu3.5+esm1","1.8.3-2ubuntu3.5+esm2","1.8.3-2ubuntu3.5+esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"cups-browsed","binary_version":"1.8.3-2ubuntu3.5+esm3"},{"binary_name":"cups-filters","binary_version":"1.8.3-2ubuntu3.5+esm3"},{"binary_name":"cups-filters-core-drivers","binary_version":"1.8.3-2ubuntu3.5+esm3"},{"binary_version":"1.8.3-2ubuntu3.5+esm3","binary_name":"libcupsfilters1"},{"binary_name":"libfontembed1","binary_version":"1.8.3-2ubuntu3.5+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-64611.json"}},{"package":{"name":"cups-filters","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/cups-filters?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.17.9-0ubuntu1","1.17.9-1","1.20.0-2","1.20.1-1","1.20.1-1build1","1.20.2-0ubuntu1","1.20.2-0ubuntu2","1.20.2-0ubuntu3","1.20.2-0ubuntu3.1","1.20.2-0ubuntu3.3","1.20.2-0ubuntu3.3+esm1","1.20.2-0ubuntu3.3+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.20.2-0ubuntu3.3+esm2","binary_name":"cups-browsed"},{"binary_name":"cups-filters","binary_version":"1.20.2-0ubuntu3.3+esm2"},{"binary_name":"cups-filters-core-drivers","binary_version":"1.20.2-0ubuntu3.3+esm2"},{"binary_name":"libcupsfilters1","binary_version":"1.20.2-0ubuntu3.3+esm2"},{"binary_name":"libfontembed1","binary_version":"1.20.2-0ubuntu3.3+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-64611.json"}},{"package":{"name":"cups-filters","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/cups-filters?arch=source&distro=esm-infra%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.25.11-0ubuntu1","1.25.11-1","1.25.12-1","1.25.13-1","1.26.0-1","1.26.1-1","1.26.2-1","1.27.0-1","1.27.0-2","1.27.1-1","1.27.1-2","1.27.1-3","1.27.2-1","1.27.3-1","1.27.4-1","1.27.4-1ubuntu0.2","1.27.4-1ubuntu0.3","1.27.4-1ubuntu0.4","1.27.4-1ubuntu0.4+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"cups-browsed","binary_version":"1.27.4-1ubuntu0.4+esm1"},{"binary_name":"cups-filters","binary_version":"1.27.4-1ubuntu0.4+esm1"},{"binary_name":"cups-filters-core-drivers","binary_version":"1.27.4-1ubuntu0.4+esm1"},{"binary_version":"1.27.4-1ubuntu0.4+esm1","binary_name":"libcupsfilters1"},{"binary_version":"1.27.4-1ubuntu0.4+esm1","binary_name":"libfontembed1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-64611.json"}},{"package":{"name":"cups-filters","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/cups-filters?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.28.10-2","1.28.11-1","1.28.11-2","1.28.12-1","1.28.13-0ubuntu1","1.28.14-1","1.28.15-0ubuntu1","1.28.15-0ubuntu1.2","1.28.15-0ubuntu1.3","1.28.15-0ubuntu1.4","1.28.15-0ubuntu1.5"],"ecosystem_specific":{"binaries":[{"binary_name":"cups-browsed","binary_version":"1.28.15-0ubuntu1.5"},{"binary_version":"1.28.15-0ubuntu1.5","binary_name":"cups-filters"},{"binary_name":"cups-filters-core-drivers","binary_version":"1.28.15-0ubuntu1.5"},{"binary_name":"libcupsfilters1","binary_version":"1.28.15-0ubuntu1.5"},{"binary_name":"libfontembed1","binary_version":"1.28.15-0ubuntu1.5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-64611.json"}},{"package":{"name":"cups-filters","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/cups-filters?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.0-0ubuntu1","2.0.0-0ubuntu3","2.0.0-0ubuntu4","2.0.0-0ubuntu4.1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.0-0ubuntu4.1","binary_name":"cups-filters"},{"binary_name":"cups-filters-core-drivers","binary_version":"2.0.0-0ubuntu4.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/c
