Doc Text:
A flaw was found in assimp. An attacker can exploit an integer overflow in the MD2 file parser by providing a specially crafted 3D model file with manipulated header values. When processed, this vulnerability triggers an out-of-bounds memory read, resulting in a Denial of Service (DoS) through an application crash or the potential disclosure of sensitive memory.

Description OSIDB Bzimport 2026-10-28 02:33:26 UTC 
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.
