{"id":"UBUNTU-CVE-2023-30630","details":"Dmidecode before 3.5 allows -dump-bin to overwrite a local file. This has security relevance because, for example, execution of Dmidecode via Sudo is plausible. NOTE: Some third parties have indicated the fix in 3.5 does not adequately address the vulnerability. The argument is that the proposed patch prevents dmidecode from writing to an existing file. However, there are multiple attack vectors that would not require overwriting an existing file that would provide the same level of unauthorized privilege escalation (e.g. creating a new file in /etc/cron.hourly).","modified":"2026-05-20T16:13:35.769716125Z","published":"2023-04-13T16:15:00Z","upstream":["CVE-2023-30630"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-30630"},{"type":"REPORT","url":"https://lists.nongnu.org/archive/html/dmidecode-devel/2023-03/msg00003.html"},{"type":"REPORT","url":"https://github.com/adamreiser/dmiwrite"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-30630"}],"affected":[{"package":{"name":"dmidecode","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/dmidecode?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.12-2","binary_name":"dmidecode"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"dmidecode","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/dmidecode?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12-4","3.0-2","3.0-2ubuntu0.1","3.0-2ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_name":"dmidecode","binary_version":"3.0-2ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"dmidecode","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/dmidecode?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1-1","3.1-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1-1ubuntu0.1","binary_name":"dmidecode"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"dmidecode","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/dmidecode?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2-2","3.2-3"],"ecosystem_specific":{"binaries":[{"binary_name":"dmidecode","binary_version":"3.2-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"cpu-x","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/cpu-x?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.4-1","3.2.4-2","3.2.4-3","3.2.4-3build1","3.2.4-3build2"],"ecosystem_specific":{"binaries":[{"binary_name":"cpu-x","binary_version":"3.2.4-3build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"cpu-x","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/cpu-x?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.1.0-2","4.2.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"cpu-x","binary_version":"4.2.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"dmidecode","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/dmidecode?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3-3","3.3-3ubuntu0.1","3.3-3ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_name":"dmidecode","binary_version":"3.3-3ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"cpu-x","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/cpu-x?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.5.3-1","5.0.3-2","5.0.3-2build1","5.0.3-2build2"],"ecosystem_specific":{"binaries":[{"binary_name":"cpu-x","binary_version":"5.0.3-2build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"cpu-x","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/cpu-x?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.1.3-0.1","5.2.0-0.4","5.3.1-0.2","5.3.1-0.3"],"ecosystem_specific":{"binaries":[{"binary_version":"5.3.1-0.3","binary_name":"cpu-x"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30630.json"}},{"package":{"name":"cpu-x","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/cpu-x?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.3.1-0.3","5.4.0-0.2"],"ecosystem_specific":{"binaries":[{"binary_version":"5.4.0-0.2","binary_name":"cpu-x"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main
