Local process crash via unchecked animation write
Published Jun 1, 2026 · Updated Jun 1, 2026
Heap-based buffer overflow in Assimp 6.0.0 through 6.0.4 allows local users to crash a process via a malformed Half-Life 1 MDL file. In HL1MDLLoader::read_animations, the parser allocates a one-entry animation array but writes a second pointer past its end without validating the array boundary. Exploitation requires a local user or local workflow to make an application import the crafted file; the published proof of concept demonstrates a process crash.
