openslide — security advisory
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.
