CVE-2026-117608 | BDVDB-2026-397251 Detail
assimpassimp
Description#
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.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact none, availability impact high. Attack vector: local.
Weaknesses#
- CWE-190 Integer Overflow or Wraparound
