{"id":"CVE-2026-111130","summary":"OpenSlide through 4.0.1 Heap Out-of-Bounds Read via MIRAX get_tile_position","details":"OpenSlide through 4.0.1 contains a heap out-of-bounds read vulnerability in the MIRAX reader that allows attackers to read past the slide_positions array via crafted Slidedat.ini values. Attackers can supply a MIRAX slide whose CameraImageDivisionsPerSide does not evenly divide the image counts, crashing applications that open it and corrupting tile geometry.","modified":"2026-10-17T02:48:26.226512382Z","published":"2026-10-15T18:57:25.805Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111130.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-125"]},"references":[{"type":"WEB","url":"https://github.com"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111130.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111130"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openslide-through-4.0.1-heap-out-of-bounds-read-via-mirax-get-tile-position"},{"type":"PACKAGE","url":"https://github.com/openslide/openslide"},{"type":"ARTICLE","url":"https://github.com/openslide/openslide/blob/fe79a9713bef2bfd64bbfefd15704060764b1274/src/openslide-vendor-mirax.c#L1033-L1034"},{"type":"ARTICLE","url":"https://github.com/openslide/openslide/blob/fe79a9713bef2bfd64bbfefd15704060764b1274/src/openslide-vendor-mirax.c#L611-L635"},{"type":"ARTICLE","url":"https://hackmd.io/@haind-pwn/openslide-mirax-slide-position-index-oob-read"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openslide/openslide","events":[{"introduced":"0"},{"fixed":"fe79a9713bef2bfd64bbfefd15704060764b1274"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"4.0.1"},{"fixed":"4.0.1"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v4.0.0","v3.4.1","v3.4.0","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.2.6","v3.2.5","v3.2.4","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.1","v3.1.0","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.3.1","v2.3.0","v2.2.1","v2.2.0","v2.1.0","v2.0.0","v1.1.1","v1.1.0","v1.0.0","v0.5.0","v0.4.2","v0.4-old","v0.4.1-old","v0.3-old","v0.2.0-old","v0.1.0-old"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111130.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
