{"id":"CVE-2025-43718","details":"Poppler 24.06.1 through 25.x before 25.04.0 allows stack consumption and a SIGSEGV via deeply nested structures within the metadata (such as GTS_PDFEVersion) of a PDF document, e.g., a regular expression for a long pdfsubver string. This occurs in Dict::lookup, Catalog::getMetadata, and associated functions in PDFDoc, with deep recursion in the regex executor (std::__detail::_Executor).","modified":"2026-08-12T03:51:36.557058794Z","published":"2025-10-01T00:00:00Z","related":["SUSE-SU-2025:3779-1","SUSE-SU-2025:3898-1","SUSE-SU-2025:3900-1","SUSE-SU-2025:3910-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/43xxx/CVE-2025-43718.json","cna_assigner":"mitre","cwe_ids":["CWE-674"]},"references":[{"type":"WEB","url":"https://github.com/ShadowByte1/CVE-Reports/blob/main/CVE-2025-43718.md"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/43xxx/CVE-2025-43718.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-43718"},{"type":"FIX","url":"https://gitlab.freedesktop.org/poppler/poppler/-/commit/f54b815672117c250420787c8c006de98e8c7408"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.freedesktop.org/poppler/poppler","events":[{"introduced":"c670e8e1fd8cc4630b8e02f195681027edd4c19a"},{"fixed":"a0f064e8393d0f9dc62d630f08d2c961b37c5a27"}],"database_specific":{"extracted_events":[{"introduced":"24.06.1"},{"fixed":"25.04.0"}],"source":"AFFECTED_FIELD"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-43718.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
