{"schema":"threatline.record/2","record":{"id":"CVE-2026-103678","aliases":[],"summary":"Tnef: heap out-of-bounds read in get_rtf_data_from_buf() via uncompressed rtf mapi value","details":"A flaw was found in tnef. An attacker can exploit this vulnerability by providing a specially crafted file containing uncompressed Rich Text Format (RTF) data. Because the application fails to properly validate input buffer boundaries before copying data in get_rtf_data_from_buf(), reading beyond the allocated memory occurs. This flaw can cause the application to crash, leading to a Denial of Service (DoS), or leak sensitive memory contents into extracted output files.","categories":["Unclassified"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-103678","source_modified_at":"2026-10-01T15:00:19.812Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":null,"vendor":null,"versions":[{"status":"affected","version":"0","versionType":"semver","lessThanOrEqual":"1.4.18"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":5.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00239,"percentile":0.14116,"score_date":"2026-10-23"},"published_at":"2026-10-01T11:34:48.652Z","modified_at":"2026-10-01T15:00:19.812Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-103678","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T15:00:19.812Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-103678","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-103678","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2544476","tags":["issue-tracking","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://github.com/verdammelt/tnef"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-01T15:00:11.354180Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-01T15:00:19.812Z","content_hash":"7b50a1faf986bb77319d0a725c5520236bce6b2d22a002ae5bbaba73052b0e31"}}
