{"id":"UBUNTU-CVE-2025-14819","details":"When doing TLS related transfers with reused easy or multi handles and altering the  `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcurl find and accept a trust chain that it otherwise would not.","modified":"2026-04-22T15:31:37.780405Z","published":"2026-01-06T07:00:00Z","related":["USN-8062-1"],"upstream":["CVE-2025-14819"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-14819"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-14819"},{"type":"REPORT","url":"https://curl.se/docs/CVE-2025-14819.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8062-1"}],"affected":[{"package":{"name":"curl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/curl@8.5.0-2ubuntu10.7?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.5.0-2ubuntu10.7"}]}],"versions":["8.2.1-1ubuntu3","8.2.1-1ubuntu3.1","8.4.0-2ubuntu1","8.5.0-2ubuntu1","8.5.0-2ubuntu2","8.5.0-2ubuntu8","8.5.0-2ubuntu9","8.5.0-2ubuntu10","8.5.0-2ubuntu10.1","8.5.0-2ubuntu10.2","8.5.0-2ubuntu10.3","8.5.0-2ubuntu10.4","8.5.0-2ubuntu10.5","8.5.0-2ubuntu10.6"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"curl","binary_version":"8.5.0-2ubuntu10.7"},{"binary_name":"libcurl3t64-gnutls","binary_version":"8.5.0-2ubuntu10.7"},{"binary_name":"libcurl4t64","binary_version":"8.5.0-2ubuntu10.7"}],"priority_reason":"This is rated as being low severity by Curl developers"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-14819.json"}},{"package":{"name":"curl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/curl@8.14.1-2ubuntu1.1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.14.1-2ubuntu1.1"}]}],"versions":["8.12.1-3ubuntu1","8.13.0-5ubuntu1","8.14.1-1ubuntu2","8.14.1-1ubuntu3","8.14.1-2ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"curl","binary_version":"8.14.1-2ubuntu1.1"},{"binary_version":"8.14.1-2ubuntu1.1","binary_name":"libcurl3t64-gnutls"},{"binary_name":"libcurl4t64","binary_version":"8.14.1-2ubuntu1.1"}],"priority_reason":"This is rated as being low severity by Curl developers"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-14819.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"low"}]}
