CVE-2026-111130 [MEDIUM] – OpenSlide through 4.0.1 contains a heap out-of-bounds read vulnerability in the MIRAX read

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.
