CVE-2026-117608 · Assimp through 6.0.5 Heap Out-of-Bounds Read via MD2 Importer Integer Overflow

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Assimp through 6.0.5 contains an integer overflow vulnerability in MD2Importer::ValidateHeader() that allows attackers to bypass frame table bounds checks using crafted header fields. Attackers can supply a malicious .md2 file whose numFrames and numVertices values wrap the 32-bit size check, causing heap out-of-bounds reads that crash applications or expose adjacent heap memory.
