Application crash via unchecked COLLADA accessor bounds
Published Jan 20, 2023 · Updated Apr 3, 2025
Use-after-free in the COLLADA importer of assimp 5.1.4 allows attackers to crash applications that process a crafted model file. ReadPrimitives fails to verify that accessor offset, count, and stride values fit the backing value array before ExtractDataObjectFromChannel reads from it. The flaw is reached when an application imports malformed COLLADA data; the published proof of concept demonstrates a segmentation fault rather than code execution.
