Submit #735232: Open Asset Import Library Assimp 6.0.2 Use After Freeinfo

TitleOpen Asset Import Library Assimp 6.0.2 Use After Free
DescriptionA heap-use-after-free vulnerability exists in the LWO file parser of Assimp. When processing a specially crafted LWO file via the assimp extract command, the application may access freed heap memory in Assimp::LWOImporter::FindUVChannels(), leading to a crash. This vulnerability can be triggered by user-supplied LWO files and may result in denial of service.
