The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in OpenSSL does not call this function however third party applications might call these functions on untrusted data.","affected":[{"package":{"name":"openssl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/openssl@3.0.2-0ubuntu1.8?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.2-0ubuntu1.8"}]}],"versions":["1.1.1l-1ubuntu1","3.0.0-1ubuntu1","3.0.1-0ubuntu1","3.0.2-0ubuntu1","3.0.2-0ubuntu1.1","3.0.2-0ubuntu1.2","3.0.2-0ubuntu1.4","3.0.2-0ubuntu1.5","3.0.2-0ubuntu1.6","3.0.2-0ubuntu1.7"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libssl3","binary_version":"3.0.2-0ubuntu1.8"},{"binary_name":"openssl","binary_version":"3.0.2-0ubuntu1.8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-0216.json"}}],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-0216"},{"type":"REPORT","url":"https://www.openssl.org/news/secadv/20230207.txt"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5844-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-0216"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"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"}]}
