{"id":"CVE-2018-20751","details":"An issue was discovered in crop_page in PoDoFo 0.9.6. For a crafted PDF document, pPage-\u003eGetObject()-\u003eGetDictionary().AddKey(PdfName(\"MediaBox\"),var) can be problematic due to the function GetObject() being called for the pPage NULL pointer object. The value of pPage at this point is 0x0, which causes a NULL pointer dereference.","modified":"2026-04-10T04:07:41.826790Z","published":"2019-02-04T19:29:00.240Z","related":["MGASA-2020-0294","SUSE-SU-2019:1849-1","openSUSE-SU-2024:11178-1","openSUSE-SU-2025:15521-1"],"references":[{"type":"EVIDENCE","url":"https://research.loginsoft.com/bugs/null-pointer-dereference-vulnerability-in-crop_page-podofo-0-9-6/"},{"type":"EVIDENCE","url":"https://sourceforge.net/p/podofo/tickets/33/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/podofo/podofo","events":[{"introduced":"0"},{"last_affected":"5abb212ed25241496a076480ff6cb54d6e17df71"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"0.9.6"}]}}],"versions":["0.9.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-20751.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
