CVE-2026-111130— OpenSlide through 4.0.1 Heap Out-of-Bounds Read via MIRAX get_tile_position

Quick assessment

Affected
OpenSlide openslide
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenSlide 4.0.1 及更早版本中，MIRAX 阅读器存在一个堆缓冲区越界读取漏洞。攻击者可以通过构造 Slidedat.ini 文件中的值，读取 slide_positions 数组边界之外的数据。具体而言，攻击者可提供一个 MIRAX 幻灯片，其 CameraImageDivisionsPerSide 的值不能整除图像计数，从而导致打开该文件的应用程序崩溃，并破坏图块（tile）几何结构。
