An update for python-pdfminer.six is now available for openEuler-24.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-4210 Final 1.0 1.0 2026-09-30 Initial 2026-09-30 2026-09-30 openEuler SA Tool V1.0 2026-09-30 python-pdfminer.six security update An update for python-pdfminer.six is now available for openEuler-24.03-LTS-SP3 PDF parser and analyzer. Security Fix(es): 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.(CVE-2025-70559) An update for python-pdfminer.six is now available for master/openEuler-24.03-LTS/openEuler-24.03-LTS-Next/openEuler-24.03-LTS-SP1/openEuler-24.03-LTS-SP2/openEuler-24.03-LTS-SP3/openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of medium.
