Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
