Heap corruption via unchecked DNN operand indexes
Published Jun 16, 2020 · Updated Aug 4, 2024
Heap-based buffer overflow in FFmpeg through 4.3 allows remote attackers to corrupt process memory through a crafted DNN model. The native DNN loader uses model-supplied operand indexes to select operand structures before avio_get_str writes a model-supplied name, without first verifying that the indexes are within the allocated operand array. Exploitation requires an application or user to load attacker-controlled model data and can crash FFmpeg or corrupt its process memory.
