Application crash via unchecked MD5 buffer read
Published Nov 21, 2024 · Updated Nov 26, 2024
Heap-buffer overflow in Assimp 5.4.3's MD5 parser allows local users to crash importing applications via a malformed model file. SkipSpacesAndLineEnd in MD5Parser.h dereferences its buffer pointer while skipping whitespace without first confirming that it remains before bufferEnd. An application must pass attacker-controlled MD5 data to the importer; the demonstrated consequence is a process crash from an out-of-bounds read.
