{"id":"UBUNTU-CVE-2025-70559","details":"pdfminer.six before 20251230 contains an insecure deserialization vulnerability in the CMap loading mechanism. The library uses Python pickle to deserialize CMap cache files without validation. An attacker with the ability to place a malicious pickle file in a location accessible to the application can trigger arbitrary code execution or privilege escalation when the file is loaded by a trusted process. This is caused by an incomplete patch to CVE-2025-64512.","modified":"2026-02-13T18:13:26.496576Z","published":"2026-02-03T18:16:00Z","upstream":["CVE-2025-70559"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-70559"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-70559"},{"type":"REPORT","url":"https://github.com/pdfminer/pdfminer.six/security/advisories/GHSA-f83h-ghpp-7wcc"},{"type":"REPORT","url":"https://github.com/pdfminer/pdfminer.six/pull/1172"},{"type":"REPORT","url":"https://github.com/advisories/GHSA-f83h-ghpp-7wcc"}],"affected":[{"package":{"name":"pdfminer","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/pdfminer@20140328+dfsg-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20110515+dfsg-1","20140328+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pdfminer-data","binary_version":"20140328+dfsg-1"},{"binary_name":"python-pdfminer","binary_version":"20140328+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70559.json"}},{"package":{"name":"pdfminer","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/pdfminer@20140328+dfsg-1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20140328+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pdfminer-data","binary_version":"20140328+dfsg-1"},{"binary_name":"python-pdfminer","binary_version":"20140328+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70559.json"}},{"package":{"name":"pdfminer","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/pdfminer@20191020+dfsg-2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20181108+dfsg-3","20191020+dfsg-1","20191020+dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_name":"pdfminer-data","binary_version":"20191020+dfsg-2"},{"binary_name":"python3-pdfminer","binary_version":"20191020+dfsg-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70559.json"}},{"package":{"name":"pdfminer","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/pdfminer@20220319+dfsg-1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20200726-1","20201018+dfsg-1","20220319+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pdfminer-data","binary_version":"20220319+dfsg-1"},{"binary_name":"python3-pdfminer","binary_version":"20220319+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70559.json"}},{"package":{"name":"pdfminer","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/pdfminer@20221105+dfsg-1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20221105+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pdfminer-data","binary_version":"20221105+dfsg-1"},{"binary_name":"python3-pdfminer","binary_version":"20221105+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70559.json"}},{"package":{"name":"pdfminer","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/pdfminer@20221105+dfsg-1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20221105+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pdfminer-data","binary_version":"20221105+dfsg-1"},{"binary_name":"python3-pdfminer","binary_version":"20221105+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70559.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:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
