Assimp through 6.0.6 Integer Overflow via OgreBinarySerializer::ReadSubMesh

Published Nov 15, 2026 CVSS 4.0 · 6.8 Medium EPSS n/a KEV · Not listed

Description

Assimp through 6.0.6 contains an integer overflow vulnerability in OgreBinarySerializer::ReadSubMesh that allows attackers to crash applications by supplying crafted Ogre binary .mesh files. Attackers can set a large index count so the 32-bit buffer size wraps, causing a segmentation fault in aiMesh::~aiMesh() during scene teardown.
