{"id":"ALPINE-CVE-2022-30524","details":"There is an invalid memory access in the TextLine class in TextOutputDev.cc in Xpdf 4.0.4 because the text extractor mishandles characters at large y coordinates. It can be triggered by (for example) sending a crafted pdf file to the pdftotext binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.","modified":"2026-11-03T07:30:50.280058876Z","published":"2022-05-09T18:15:09.343Z","upstream":["CVE-2022-30524"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-30524"}],"affected":[{"package":{"name":"xpdf","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/xpdf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.05-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-30524.json"}},{"package":{"name":"xpdf","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/xpdf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.05-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-30524.json"}},{"package":{"name":"xpdf","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/xpdf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.05-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-30524.json"}},{"package":{"name":"xpdf","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/xpdf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.05-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-30524.json"}},{"package":{"name":"xpdf","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xpdf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.05-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-30524.json"}},{"package":{"name":"xpdf","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xpdf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.05-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-30524.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
