TitleOpen Asset Import Library Assimp Assimp Version: 6.0.2 / master commit 0581ed5 Heap-based Buffer Overflow
DescriptionUsing GDB, I inspected the parser state at the crash site. The in pointer was found to be greater than the end pointer (in > end), which violates the contract assumed by functions like getNextSeparator. As a result, the loop condition while (in != end && !isSeparator(*in)) attempts to dereference *in past the allocated buffer. This likely originates from an earlier function (parseDataList, parseStructureBody, or lookForNextToken) that incorrectly advanced in beyond end.
