{"id":"UBUNTU-CVE-2018-12115","details":"In all versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0 when used with UCS-2 encoding (recognized by Node.js under the names `'ucs2'`, `'ucs-2'`, `'utf16le'` and `'utf-16le'`), `Buffer#write()` can be abused to write outside of the bounds of a single `Buffer`. Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written.","modified":"2026-01-30T01:43:40.148407Z","published":"2018-08-21T12:29:00Z","related":["USN-4796-1"],"upstream":["CVE-2018-12115"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-12115"},{"type":"REPORT","url":"https://nodejs.org/en/blog/vulnerability/august-2018-security-releases/"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4796-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-12115"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/nodejs@0.10.25~dfsg2-2ubuntu1.2+esm2?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.15~dfsg1-4","0.10.21~dfsg1-1","0.10.22~dfsg1-2","0.10.23~dfsg1-1","0.10.23~dfsg1-2","0.10.23~dfsg1-3","0.10.24~dfsg1-1","0.10.25~dfsg2-2","0.10.25~dfsg2-2ubuntu1","0.10.25~dfsg2-2ubuntu1.2","0.10.25~dfsg2-2ubuntu1.2+esm1","0.10.25~dfsg2-2ubuntu1.2+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.25~dfsg2-2ubuntu1.2+esm2","binary_name":"nodejs"},{"binary_version":"0.10.25~dfsg2-2ubuntu1.2+esm2","binary_name":"nodejs-dev"},{"binary_version":"0.10.25~dfsg2-2ubuntu1.2+esm2","binary_name":"nodejs-legacy"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-12115.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/nodejs@4.2.6~dfsg-1ubuntu4.2+esm3?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.25~dfsg2-2ubuntu1","4.2.2~dfsg-1","4.2.3~dfsg-1","4.2.4~dfsg-1ubuntu1","4.2.4~dfsg-2","4.2.6~dfsg-1ubuntu1","4.2.6~dfsg-1ubuntu4","4.2.6~dfsg-1ubuntu4.1","4.2.6~dfsg-1ubuntu4.2","4.2.6~dfsg-1ubuntu4.2+esm1","4.2.6~dfsg-1ubuntu4.2+esm2","4.2.6~dfsg-1ubuntu4.2+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"4.2.6~dfsg-1ubuntu4.2+esm3","binary_name":"nodejs"},{"binary_version":"4.2.6~dfsg-1ubuntu4.2+esm3","binary_name":"nodejs-dev"},{"binary_version":"4.2.6~dfsg-1ubuntu4.2+esm3","binary_name":"nodejs-legacy"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-12115.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/nodejs@8.10.0~dfsg-2ubuntu0.4+esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.10.0~dfsg-2ubuntu0.4+esm1"}]}],"versions":["6.11.4~dfsg-1ubuntu1","6.11.4~dfsg-1ubuntu2","6.12.0~dfsg-1ubuntu1","6.12.0~dfsg-2ubuntu1","6.12.0~dfsg-2ubuntu2","8.10.0~dfsg-2","8.10.0~dfsg-2ubuntu0.2","8.10.0~dfsg-2ubuntu0.3","8.10.0~dfsg-2ubuntu0.4"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"8.10.0~dfsg-2ubuntu0.4+esm1","binary_name":"nodejs"},{"binary_version":"8.10.0~dfsg-2ubuntu0.4+esm1","binary_name":"nodejs-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-12115.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
