{"id":"UBUNTU-CVE-2023-46233","details":"crypto-js is a JavaScript library of crypto standards. Prior to version 4.2.0, crypto-js PBKDF2 is 1,000 times weaker than originally specified in 1993, and at least 1,300,000 times weaker than current industry standard. This is because it both defaults to SHA1, a cryptographic hash algorithm considered insecure since at least 2005, and defaults to one single iteration, a 'strength' or 'difficulty' value specified at 1,000 when specified in 1993. PBKDF2 relies on iteration count as a countermeasure to preimage and collision attacks. If used to protect passwords, the impact is high. If used to generate signatures, the impact is high. Version 4.2.0 contains a patch for this issue. As a workaround, configure crypto-js to use SHA256 with at least 250,000 iterations.","modified":"2026-02-04T04:18:40.892281Z","published":"2023-10-25T21:15:00Z","related":["USN-6753-1"],"upstream":["CVE-2023-46233"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-46233"},{"type":"REPORT","url":"https://github.com/brix/crypto-js/security/advisories/GHSA-xwcq-pm8m-c4vf"},{"type":"REPORT","url":"https://github.com/brix/crypto-js/commit/421dd538b2d34e7c24a5b72cc64dc2b9167db40a"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-46233"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6753-1"}],"affected":[{"package":{"name":"cryptojs","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/cryptojs@3.1.2+dfsg-2ubuntu0.16.04.1~esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2+dfsg-2ubuntu0.16.04.1~esm1"}]}],"versions":["3.1.2+dfsg-1","3.1.2+dfsg-2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"3.1.2+dfsg-2ubuntu0.16.04.1~esm1","binary_name":"libjs-cryptojs"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46233.json"}},{"package":{"name":"cryptojs","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/cryptojs@3.1.2+dfsg-2ubuntu0.18.04.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2+dfsg-2ubuntu0.18.04.1~esm1"}]}],"versions":["3.1.2+dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-cryptojs","binary_version":"3.1.2+dfsg-2ubuntu0.18.04.1~esm1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46233.json"}},{"package":{"name":"cryptojs","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/cryptojs@3.1.2+dfsg-2ubuntu0.20.04.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2+dfsg-2ubuntu0.20.04.1"}]}],"versions":["3.1.2+dfsg-2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libjs-cryptojs","binary_version":"3.1.2+dfsg-2ubuntu0.20.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46233.json"}},{"package":{"name":"cryptojs","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/cryptojs@3.1.2+dfsg-3ubuntu0.22.04.1~esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2+dfsg-3ubuntu0.22.04.1~esm1"}]}],"versions":["3.1.2+dfsg-3"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"libjs-cryptojs","binary_version":"3.1.2+dfsg-3ubuntu0.22.04.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46233.json"}},{"package":{"name":"cryptojs","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/cryptojs@3.1.2+dfsg-4?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.2+dfsg-3","3.1.2+dfsg-4"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-cryptojs","binary_version":"3.1.2+dfsg-4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46233.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
