| Title | https://github.com/assimp/assimp assimp v5.4.3 Heap-based Buffer Overflow |
|---|
| Description | A heap-buffer-overflow vulnerability was discovered in the Assimp::BaseImporter::ConvertToUTF8 function within the Assimp Library. This issue occurs when processing certain malformed files, leading to an out-of-bounds read and potential application crash. The vulnerability arises in the Assimp::BaseImporter::ConvertToUTF8 function defined in BaseImporter.cpp at line 392. The function calls problematical utf32to8 defined in assimp/contrib/utf8cpp/source/utf8/checked.h, resulting in a read operation beyond the allocated memory. |
