{"id":"ALPINE-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":"2026-10-27T08:31:20.329228254Z","published":"2019-02-04T19:29:00.240Z","upstream":["CVE-2018-20751"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2018-20751"}],"affected":[{"package":{"name":"podofo","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}},{"package":{"name":"podofo","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/podofo?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-20751.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
