{"id":"UBUNTU-CVE-2023-33546","details":"** DISPUTED ** Janino 3.1.9 and earlier are subject to denial of service (DOS) attacks when using the expression evaluator.guess parameter name method. If the parser runs on user-supplied input, an attacker could supply content that causes the parser to crash due to a stack overflow. NOTE: this is disputed by multiple parties because Janino is not intended for use with untrusted input.","modified":"2023-06-01T13:15:00Z","published":"2023-06-01T13:15:00Z","withdrawn":"2025-06-23T15:56:52Z","references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-33546"},{"type":"REPORT","url":"https://github.com/janino-compiler/janino/issues/201"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-33546"}],"affected":[{"package":{"name":"janino","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/janino"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.0-2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-33546.json"}},{"package":{"name":"janino","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/janino"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.0-2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-33546.json"}},{"package":{"name":"janino","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/janino"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.0-2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-33546.json"}},{"package":{"name":"janino","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/janino"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.0-2.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-33546.json"}},{"package":{"name":"janino","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/janino"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.0-2.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-33546.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
