{"id":"UBUNTU-CVE-2025-66453","details":"Rhino is an open-source implementation of JavaScript written entirely in Java. Prior to 1.8.1, 1.7.15.1, and 1.7.14.1, when an application passed an attacker controlled float poing number into the toFixed() function, it might lead to high CPU consumption and a potential Denial of Service. Small numbers go through this call stack: NativeNumber.numTo \u003e DToA.JS_dtostr \u003e DToA.JS_dtoa \u003e DToA.pow5mult where pow5mult attempts to raise 5 to a ridiculous power. This vulnerability is fixed in 1.8.1, 1.7.15.1, and 1.7.14.1.","modified":"2026-05-20T16:23:41.959312956Z","published":"2025-12-03T20:16:00Z","upstream":["CVE-2025-66453"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-66453"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-66453"},{"type":"REPORT","url":"https://github.com/mozilla/rhino/security/advisories/GHSA-3w8q-xq97-5j7x"}],"affected":[{"package":{"name":"rhino","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/rhino?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7R4-3"],"ecosystem_specific":{"binaries":[{"binary_name":"librhino-java","binary_version":"1.7R4-3"},{"binary_version":"1.7R4-3","binary_name":"rhino"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66453.json"}},{"package":{"name":"rhino","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/rhino?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.7.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librhino-java","binary_version":"1.7.7.1-1"},{"binary_name":"rhino","binary_version":"1.7.7.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66453.json"}},{"package":{"name":"rhino","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/rhino?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.7.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librhino-java","binary_version":"1.7.7.1-1"},{"binary_version":"1.7.7.1-1","binary_name":"rhino"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66453.json"}},{"package":{"name":"rhino","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rhino?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.7.2-3"],"ecosystem_specific":{"binaries":[{"binary_name":"librhino-java","binary_version":"1.7.7.2-3"},{"binary_version":"1.7.7.2-3","binary_name":"rhino"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66453.json"}},{"package":{"name":"rhino","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rhino?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.14-2.1"],"ecosystem_specific":{"binaries":[{"binary_name":"librhino-java","binary_version":"1.7.14-2.1"},{"binary_version":"1.7.14-2.1","binary_name":"rhino"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66453.json"}},{"package":{"name":"rhino","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rhino?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.15-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librhino-java","binary_version":"1.7.15-1"},{"binary_version":"1.7.15-1","binary_name":"rhino"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66453.json"}},{"package":{"name":"rhino","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rhino?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.15-1","1.7.15-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"librhino-java","binary_version":"1.7.15-1build1"},{"binary_version":"1.7.15-1build1","binary_name":"rhino"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-66453.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
