Heap-based buffer overflow vulnerability in Assimp versions prior to 5.4.2 allows a local attacker to execute arbitrary code by inputting a specially crafted file into the product.
The product writes data past the end, or before the beginning, of the intended buffer.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
