{"id":"UBUNTU-CVE-2026-119204","details":"pypdf is a free and open-source pure-python PDF library. Prior to 6.21.4, pypdf can consume excessive memory while parsing a crafted PDF page tree containing many shared resources. Page-tree flattening copies page dictionary and inherited resource entries without a document-wide entry budget, allowing the crafted resource structure to cause disproportionate allocations. This issue is fixed in version 6.21.4.","modified":"2026-11-04T03:30:28.493503357Z","published":"2026-10-30T00:00:00Z","upstream":["CVE-2026-119204"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119204"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119204"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/commit/ea4ac663133f1b3de1d7a8f2e6fa239802fde79e"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/pull/4290"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/releases/tag/6.21.4"},{"type":"REPORT","url":"https://github.com/py-pdf/pypdf/security/advisories/GHSA-cggf-277g-3q54"}],"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_name":"python3-pypdf","binary_version":"4.0.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119204.json"}},{"package":{"name":"pypdf","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/pypdf?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.9.2-1","6.9.2-2"],"ecosystem_specific":{"binaries":[{"binary_version":"6.9.2-2","binary_name":"python3-pypdf"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119204.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_version":"6.9.2-1","binary_name":"python3-pypdf"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119204.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
