{"id":"CVE-2019-12493","details":"A stack-based buffer over-read exists in PostScriptFunction::transform in Function.cc in Xpdf 4.01.01 because GfxSeparationColorSpace and GfxDeviceNColorSpace mishandle tint transform functions.

It might allow an attacker to cause Denial of Service or leak memory data.","modified":"2026-03-12T23:00:12.813375Z","published":"2019-05-31T02:29:00.227Z","references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2019/09/msg00033.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DJJD7X3ES7ZHJUY2R3DAVCJPV23R64VK/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FWEWFUVITPA3Y6F4A5SJSROKYT7PRH7Q/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TNIJWRYTCLGV35WGIHYTMMOPEEOOTIPT/"},{"type":"EVIDENCE","url":"https://forum.xpdfreader.com/viewtopic.php?f=3&t=41806"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.01.01"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-12493.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H"}]}
