{"schema":"threatline.record/2","record":{"id":"CVE-2017-20286","aliases":[],"summary":"DevIL through 1.8.0 Heap Buffer Overflow via GIF iGetPalette","details":"DevIL through 1.8.0 contains a heap-based buffer overflow in iGetPalette() in il_gif.cpp that allows attackers to write beyond a 768-byte palette buffer when loading GIF images. Attackers can supply a crafted two-frame GIF whose second frame uses disposal method 1 with a local colour table, writing up to 384 controlled bytes past the heap allocation and possibly executing code.","categories":["Unclassified"],"product":"DevIL","vendor":"DentonW","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2017-20286","source_modified_at":"2026-10-14T15:55:35.957Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"DevIL","vendor":"DentonW","versions":[{"version":"0","lessThanOrEqual":"1.8.0","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00202,"percentile":0.09554,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:16:27.547Z","modified_at":"2026-10-14T15:55:35.957Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2017-20286","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T15:55:35.957Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2017-20286","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/DentonW/DevIL/issues/67","tags":["issue-tracking"]},{"source":"CVE List","url":"https://hackmd.io/@haind-pwn/devil-gif-palette-reuse-heap-overflow","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://github.com/DentonW/DevIL/blob/a2d9193fed0c7f93519c0c4c28b3348e0cb5759b/DevIL/src-IL/src/il_gif.cpp#L189-L226","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/DentonW/DevIL/blob/a2d9193fed0c7f93519c0c4c28b3348e0cb5759b/DevIL/src-IL/src/il_gif.cpp#L314-L324","tags":["technical-description"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/devil-through-1.8.0-heap-buffer-overflow-via-gif-igetpalette","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-14T14:52:04.580800Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T15:55:35.957Z","content_hash":"6d4616d8e88db7fb9f453f76570f5dfd8a766e8ae12a4adeb6e9f44b645fb0e5"}}
