Attackers can supply a crafted FITS file with a SUBTRACTIVE_DITHER_1 compressed image, read through fits_open_file() and fits_read_pix(), to cause crashes or leak heap contents in decoded pixels.","categories":["Unclassified"],"product":"cfitsio","vendor":"HEASARC","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-111124","source_modified_at":"2026-10-15T18:57:21.328Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"cfitsio","vendor":"HEASARC","versions":[{"version":"0","lessThanOrEqual":"4.7.0","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00171,"percentile":0.06182,"score_date":"2026-10-23"},"published_at":"2026-10-15T18:57:21.328Z","modified_at":"2026-10-15T18:57:21.328Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-111124","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T18:57:21.328Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-111124","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://hackmd.io/@haind-pwn/cfitsio-zdither0-dither-seed-oob-read","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/HEASARC/cfitsio/blob/d6d27653740864a0483e74cff23c53e34e1dceee/imcompress.c#L5353-L5362","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/HEASARC/cfitsio/blob/d6d27653740864a0483e74cff23c53e34e1dceee/imcompress.c#L7495-L7516","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/HEASARC/cfitsio","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/cfitsio-through-4.7.0-heap-out-of-bounds-read-via-negative-zdither0-seed","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T18:57:21.328Z","content_hash":"fe027686796f78357212d3efeadf4ed6dfed7ff8af09a4ca60a73b2fc19ee795"}}
