{"id":"UBUNTU-CVE-2025-62707","details":"pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. This has been fixed in pypdf version 6.1.3.","modified":"2026-05-20T16:23:40.646710397Z","published":"2025-10-22T22:15:00Z","upstream":["CVE-2025-62707"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-62707"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-62707"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/security/advisories/GHSA-vr63-x8vc-m265"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/pull/3501"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/commit/f2864d6dd9bac7cecd3f4f54308b25ebbfa178f8"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/releases/tag/6.1.3"}],"affected":[{"package":{"name":"pypdf","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/pypdf?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1-1","3.17.4-1","4.0.0-1","4.0.1-1","4.0.2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"4.0.2-1","binary_name":"python3-pypdf"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-62707.json"}},{"package":{"name":"pypdf","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/pypdf?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.1-1","5.4.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-pypdf","binary_version":"5.4.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-62707.json"}},{"package":{"name":"pypdf","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/pypdf?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.0-1","6.9.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-pypdf","binary_version":"6.9.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-62707.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U"},{"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"}]}
